These wide RF/IF bandwidth frequency converters, with fixed LO frequencies (block converters), are commonlyused to process millimeter signals with less expensive receivers below 18 GHz. In some applications, the resultingsignals are upconverted back into the millimeter band. The LNB series, with its 4 dB noise figure, permits opera-tion at low input signal powers. In addition, the PM noise of the converter is minimized by a phase-locked and mul-tiplied internal LO source. The block diagram shown above is a baseline configuration.

MITEQ’s Model DSS Series integrates our standard broadband double-balanced mixer designs with input limiter protectiondiodes and IF amplifiers to provide a phase- and amplitude-tracked five-channel downconverter with an integrated LOamplifier/splitter. A three-way input switch/limiter provides remote band/blanking/BIT select and protection from undesiredhigh signal levels. This module is most often used as the “front-end” of a direction-finding system using four antennas inthe azimuth, elevation or combined directions and a fifth antenna channel to resolve additional received strong “back or sidelobe” signals and to identify the receiver image response. The DSS0818 is also useful as an instantaneous frequency mon-itor with suitable input frequency to phase encoders (application notes available).

DIRECTION FINDING APPLICATIONS

Can the basic direction-finding receiver also be used to measure incoming frequency?

Yes, by first encoding the received signal into two separate outputs that have a phase difference in direct proportion to their frequency:

A large cable length difference in the two splitter outputs will yield rapidly varying phase with frequency. If theseoutputs are applied to a two-channel DF system, the output phase difference, together with knowledge of theencoder cable lengths, can be used to determine input frequency. This is the basic principle of an instanta-neous frequency monitor (IFM). In actual practice, several frequency encoders are used with progressivelygreater frequency resolution, similar to how one reads the dials of a gas or an electric meter.

APPLICATIONThis linear IF digital modulator accepts ±0.2 volts input I/Q Gaussian shaped pulses and provides QAM RF with thesame envelope shape. Less channel bandwidth is required when the modulation is shaped and the I/Q phase statesare also differentially coded (DQPSK). Input and output buffer amplifiers are provided to ensure that generator and loadmismatches do not affect quadrature accuracy and the resulting symbol error rate.

MITEQ has developed a line of comb generator multiplier products. Three models are available: SYS0118N01R,SYS0218N01R and SYS0318N01R, with output comb spacing of 1 GHz, 2 GHz and 3 GHz, respectively. Eachmodel accepts a 100 MHz input signal and produces a synchronous spectral comb. A fully integrated architecture isused to implement an internal phase-locked oscillator technique prior to exciting the multiplier, resulting in high spec-tral purity and low amplitude variation without degradation of the output signal-to-noise ratio. Options available area switched filter output for individual tone selection, higher output power and lower overall phase noise. Please con-tact MITEQ for more information.

The SYS0518N01R is a dual conversion receiver capable of translating any 4 GHz instantaneous bandwidth in the0.5 to 18 GHz RF input range to an IF center frequency of 6 GHz. By using a high side LO and MITEQ’s broadbandTB0440LW1 mixer for the first conversion, it allows image frequencies to be easily filtered without the use of a track-ing filter architecture, and allows for high image suppression not achievable from an image rejection mixer. The unitalso offers high image rejection and RF-to-IF and LO-to-IF isolation of 70 dB.

MIXER SUBSYSTEMS

Questions and Answers about...

MIXER SUBSYSTEMS

Q1: How does the Mixer Product Department define a mixer subsystem?

A1: Generally, the subsystem consists of one or more unique core mixer products from catalog sections 1 through4, with added input or output components (such as amplifiers, filters, etc.) or simply phase and amplitude matchedgroups of the core mixer product with associated power dividers for LO, RF or IF.

Q2: What advantages do the subsystems offer the customer?

A2: Subsystems or multifunction components in general are designed to customer specifications. They offer thecustomer guaranteed input/output performance without worry about the ever-present interface problems between theindividual system building blocks. By eliminating intermodule connections, the units offer smaller size and light weightalternatives to assembled connectorized or drop-in components. These multifunction modules utilize, in addition to themixer capability, our low-noise amplifier technology and our high performance, small size frequency sources. In addi-tion, limiters, switches, filters, couplers, etc., can be incorporated to satisfy the customer’s requirements. Special mul-tichannel assemblies can also be produced in gain and phase matched modules.

Q3: How are the mixer subsystems grouped in this portion of the catalog?

A3: Generally, by market and complexity, because the final cost factor influences how the integration of the sub-system is accomplished. For example, all communication subsystems are intended to lower the overall cost consis-tent with meeting minimum standards of performance, whereas the radar and military subsystems tend to emphasizesmall size with screened components and state-of-the-art performance at fair prices.

Q3.1: How does MITEQ define millimeter-wave products?

A3.1: The millimeter-wave frequency band is generally accepted to mean from 30 to 300 GHz (1 mm to 0.1 mmwavelengths). For our purpose, however, in this section of the catalog, most products cover up to 50 GHz range.Furthermore, these products tend to utilize the MITEQ core technical advantages of: low-noise RF amplifiers, widestinput and output bandwidth mixers, phase-stable oscillators and multipliers.

Q3.2: What are the core advantages of Special Mixer Department’s millimeter-wave products?

A3.2: MITEQ offers the widest input/output bandwidth millimeter-wave up- and downconverters. The most populartriple-balanced unit is TB0440LW1 with an RF and LO bandwidth of 4 to 40 GHz and an IF bandwidth of 0.5 to 20GHz. Even-harmonic units are also available with less IF bandwidth, but require an LO of only 2 to 20 GHz to down-convert the 4 to 40 GHz, with only 1 to 2 dB higher loss than fundamental mixing. Another key advantage of ourdepartment’s mixer products is the capacity to integrate the low-noise amplifiers of other MITEQ departments into asingle-interface compensated unit.

The principal market for these products is low-noise block up- and downconverters that allow theuser to perform operations at high frequencies utilizingexisting lower frequency equipment.

Q3.3: What factors influence the choice of high or low side LO placement in wideband millimeter-wave block converters?

A3.3: Generally, one tries to eliminate extra LO x RF mixing products that combine the fundamental RF with har-monics of the LO. These products are highest in level and are also independent of the RF power. For example, the3LO-RF and 2LO-RF are typically -10 and -25 dBc, respectively, below the desired LO-RF output. In general, for widebandwidth applications, the LO harmonic mixing products are much more likely to occur with low side mixing. Forother applications, where LO x RF spurious products are not an issue, one may want to avoid the spectral inversionof low side mixing by placing the LO above the RF. High side mixing is also frequently employed to eliminate theimage response of a wideband receiver without tracking filters. However, another fixed frequency mixer and LO isnecessary to make this “dual conversion” technique function. The first double-sideband mixer, IF output is chosenhigh enough in frequency to produce an image band that falls outside the input RF range. For example, with a 2 to18 GHz RF input and tracking 24 to 40 GHz LO, the IF is fixed at 22 GHz and the image (2LO - RF) is 46 to 62 GHz.A second mixer and LO would be required to downconvert the 22 GHz first IF to perhaps 1 GHz. Caution is neces-sary, of course, to reject the image response of the second mixer at 20 or 24 GHz, but this is easier with a fixed fre-quency relative to the problem of a multioctave input. The first DSB mixer for this application can be a MITEQTB0440LW1.

Q3.4: How can undesired M x N (LO x RF) spurious products be minimized for a given application,assuming that “high side mixing” and LO power are not options?

A3.4: Triple-balanced mixers traditionally yield the lowest level spur products provided that the diode quads and cir-cuit baluns are constructed to yield high interport isolation. Restricting the RF and IF operating bandwidths will alsoeliminate many spur products, provided that out-of-band signals are also filtered. The table below shows the maxi-mum possible input RF, percentage bandwidth possible before certain low order products occur. Both fixed LO oper-ations above or below the RF band are shown, each with an octave IF output bandwidth for comparison (reference =Microwave Journal - 1990)

One can see from the above table that progressively smaller RF bandwidths are required to completely avoid certainproducts. The maximum RF bandwidth is also restricted to no more than 40% for the specific case of octave IF band-width. This also avoids any overlapping of the input and output bandwidth.

Q3.5: How are the general principles of the previous questions and answers applied to a specificmillimeter-wave example?

A3.5: Figure 1 illustrates several 26 to 40 GHz block downconverters, each for the 4 to 18 GHz output band. Thespur tables associated with each LO configuration illustrate the advantages of “high side” LO mixing to avoid LO har-monic products. In addition, an octave output bandwidth mixing configuration is shown that utilizes the previous prin-ciples of reduced bandwidths to eliminate spurs. However, three separate LOs and preselectors are required. Seethe following page for Figure 1.

Q4: What are some examples of new mixer subsystems useful to the communication engineer?

A4: Sampling mixers (Model SRD0218LW4) are becoming more prevalent in compact receivers and phase-locked frequency sources because they do not require a high power microwave LO to downconvert the desired sig-nal to a low IF frequency. I/Q sampling mixers can also be used for direct demodulation of biphase signals.

In addition, a new triple-balanced Schottky mixer allows direct multioctave block downconversion of the millimeter-wave 20 to 40 GHz band into an existing 0.5 to 20 GHz receiver. This is possible by using the TB0440LW1 mixer anda MITEQ-fixed frequency (+10 dBm) LO above or below the band of interest. This mixer is also useful for upcon-verting the 0.5 to 18 GHz band into a fixed Ku-band second converter, thus eliminating the image response withouttunable filters.

Q5: What are the basic principles of passive direction finding?

A5: The block diagram below shows a method of measuring the phase angle difference between signals reach-ing amplifiers A and B. All amplitude variations are removed by the IF limiters so the system is relatively insensitiveto channel gain differences. A low DC offset double-balanced mixer is used to measure the phase difference, butsince the mixer provides the same output voltage for two different phase angles, there is a 180 degree ambiguity inthe measurement.

Alternately, one can use an I/Q phase correlator or demodulator to resolve the ambiguity. The I/Q outputs can be usedto form a convenient polar display of a received angle. I/Q phase correlators are available at microwave and lowerfrequencies, although the accuracies are usually higher over narrow bandwidths below 1 GHz.

Actual DF systems use pairs of antennas in the horizontal plane (azimuth) and vertical (elevation) plane. In addition,a fifth channel is sometimes used to resolve angular ambiguities. Frequently the antenna bandwidths are less thanthe receivers, so that input switching is required. The receiving must also be protected from high input power. Theblock diagram below illustrates a MITEQ five-channel catalog direction finding subsystem less the I/Q phase detec-tors (see MITEQ Model DSS Series).

Q6: Can the basic direction finding receiver be used to also measure incoming frequency?

A6: Yes, by first encoding the received signal into two separate outputs that have a phase difference in direct pro-portion to their frequency:

A large cable length difference in the two splitter outputs will yield rapidly varying phase with frequency. If these out-puts are applied to a two-channel DF system, the output phase difference, together with knowledge of the encodercable lengths, can be used to determine input frequency. This is the basic principle of an instantaneous frequencydiscriminator (IFM). In actual practice, several frequency encoders are used with progressively greater frequency res-olution, much in the same manner that one reads the dials of a gas or electric meter.

Q7: What advantages do sampling mixers offer relative to conventional mixers/LOs for ELINT(Electronic Intelligence Gathering) receiver designs?

A7: Basically, lower cost and power consumption, because the sampling mixer utilizes a UHF LO with internalpulse shaping from a step recovery diode to downconvert an RF at 1 to 20 times higher in frequency. The samplingmixer diodes only charge for a short instant, thus requiring low LO energy relative to the amplifier multiplier chain usedto generate the LO power required for a conventional fundamental mixer. The sampling mixer, however, has a limiton the maximum IF bandwidth equal to one half the applied LO frequency (owing to the repetitive frequency responseof this mixer). Sampling mixers can also be made in I/Q and image rejection configurations (see Q & A in phase detec-tor section).

Q8: What is meant by electronic warfare (EW) components?

A8: These are component groups that are used in systems that identify and defeat the goals of ground and mis-sile radar systems. A typical component pair might be an I/Q downconverting mixer and upconverting modulator thatalters some amplitude or frequency property of a received radar pulse and then retransmits it to act as a decoy reflec-tion. In addition, since EW systems must protect the host vehicle from many different frequency signals with quickreaction times, the operating subsystem bandwidths are wide (often 0.5 to 18 GHz). Airborne EW systems frequent-ly employ small size multiple mixers with a common output or second-stage processing receiver.

Q9: What precautions are necessary when purchasing front-end mixer components for radarreceivers?

A9: If the mixer could be subjected to high peak power from transmitter leakage, one must use an input pin diodelimiter to ensure that no more than approximately 50 mW/diode or +23 dBm per quad average power. This limit isbased upon an average thermal resistance of 160°C/watt for a diode quad mounted on a soft suspended circuit boardand maximum diode junction temperature of 125°C with an ambient temperature of 85°C. A single diode limiter avail-able on most MITEQ mixer/preamplifiers will provide protection against a 100 peak power 1 µs pulse and 1 watt aver-age power.

Q10: What choice of front-end components will maximize the dynamic range of radar receivers?

A10: The benefits of low-noise MITEQ AFS or AMF RF preamplifiers are well known and obvious in detecting min-imum signal levels. However, the maximum input signal level is often limited by the second-stage image rejectionmixer’s 1 dB compression level. A general rule of thumb for the 1 dB compression level of any Schottky barrier mixeris 5 dB less than the LO power. Therefore, if the maximum output power level of the RF preamplifier is +10 dBm, onewould need at least a +15 dBm LO power mixer to avoid restricting the dynamic range. A four-channel radar receiv-er would then require a total of +21 dBm or more LO power. The additional cost and excess noise of the required LOamplifier will impose more design restrictions. As an alternative, a MESFET image rejection mixer generally has anRF 1 dB compression point equal to the LO power, therefore, in this case, the total LO power required is +16 dBm.

The MITEQ Model ARS0506L is an example of a high dynamic range four-channel front end including the LNAs MES-FET IR mixers, IF amplifiers and matched filters. The noise figure is typically 4 dB, but, could also handle up to +5dBm of input broadband RF noise jamming before overloading. The IF filters used in this phase and amplitude trackedfront end have uniform group delay, thus ensuring that paired echoes are at least 40 dB below the main response.

MILLIMETER-WAVE BLOCK CONVERTERS

A unique method has been developed for extendingthe frequency of existing 20 GHz broadband systemsto cover the entire 26 to 40 GHz Ka-band without theneed of a tuned front-end architecture. The ModelsLNB-2640-40 and LNB-1826-30 low-noise block (LNB)converters are combined to accept inputs over the 18to 40 GHz frequency range and block convert the fullband into the 2 to 20 GHz range, as shown in Figure 1.All of the converters’ filtering and LOs are internal,including a phase-locked LO source that can belocked to an external 10 MHz reference.

With the recent proliferation of both commercial andmilitary applications throughout the Ka-band, a signif-icant need has arisen for frequency conversion equip-ment to cover these now-popular ranges. Hardwarerequirements in support of these applications includenot only the technology embedded in the systems,but also the supporting test equipment required toalign, maintain and install the developed hardware.

With commercial applications such as 38 GHz point-to-point radios generating interest in high volume, lowcost production, the obvious solution is to developcustom MMICs with millimeter-wave functions. Thiseffort is already in place at many of the large foundryoperations with 0.25 or 0.18 µm GaAs processes.Amplifier, mixer and multiplier blocks have beendeveloped and currently are being integrated to offercomplete application-specific transceiver modules atreasonable prices. Even military applications, such as35 GHz monopulse seekers, can support enough vol-ume to justify a custom MMIC development effort andare often satisfied by this route.

Although millimeter-wave MMIC technology has astrong foothold throughout the Ka-band, a host ofrequirements exist on the periphery of these volumeapplications that require more broad-based perfor-mance modules. These periphery applicationsincrease the need for broadband block conversionsystems, as shown in Figure 2.

FIGURE 2

APPLICATIONSBroadband block conversion is suitable for the testand measurement market, as well as for electronicwarfare (EW) and electronic intelligence (ELINT) sys-tems that are used to extend existing equipmentoperation into the low millimeter-wave bands.Spectrum analyzers operating from 10 kHz to 26 GHzhave been on the market for several years. The ana-lyzers are found in almost every microwave companyin the world and, unfortunately, are obsolete to userswho are shifting their focus to the higher frequencybands. An obvious solution to the reprocurement ofsuch costly test equipment is to provide an adjunctsubsystem that can easily extend the frequency ofthis existing equipment to cover the desired frequen-cy bands.

Currently, most spectrum analyzer companies offerexternal harmonic mixers to extend the performanceof their fundamental operating frequency range.However, these harmonic mixers have always beencumbersome to use, often requiring a swept LO totune the desired signal into the narrow IF band of themixer. A similar situation has also existed in broad-band military systems. Presently, thousands of field-ed electronic countermeasure and ELINT systemsare operating over the 0.5 to 18 GHz band. Twochoices are available to provide operation into Ka-band, including developing a full-up, tuned Ka-bandsystem to cover the entire frequency range from 18 to40 GHz, and adding an adjunct subsystem to theexisting system to cover only the specific narrowbands above 18 GHz.

In both applications, the ideal solution would be tofold the entire upper band into the existing lower bandto relieve the requirement for a tuned front end. This

technique satisfies the requirement for minimizingadditional hardware and the logistical impact of oper-ating an additional system in the upper band. Usingblock conversion, all of the processing of the lowerbands can be utilized throughout Ka-band with mini-mal modifications, which consist mainly of a simplefrequency offset.

BLOCK CONVERSION

Folding an entire frequency range into another is alsoknown as block frequency conversion or block con-version. The process requires only a fixed LO. Moreimportantly, the process also requires a mixer with anIF coverage that matches the bandwidth of the RFband. This IF bandwidth limitation had been the long-standing reason why this approach was never utilizedfor Ka-band. A production-level mixer that could oper-ate with an RF range from 18 to 40 GHz with an IFrange to 20 GHz was all that was required.

MIXER ADVANCES

Mixers have long been available in lower bands thathave IF coverage capable of performing broadbandblock conversions. A torroidal balun design utilizes acenter-tapped transformer to extract the IF frequency,allowing it to have overlapping RF, LO and IF fre-quency ranges. However, this approach is only usefulup to approximately 3 GHz before the performance offerrite core baluns falls off and bifilar coupling struc-tures become too small for practical use.

Above 2 GHz, the distributed or microstrip balun is uti-lized to perform the 180° transform required in a bal-anced design, as shown in Figure 3. The problem withthis balun had been that the center tap did not exist toseparate the IF from the RF or LO. As a result, diplexingand balance are needed to reject the RF or LO at the IFport in double-balanced designs. The problem with these

double-balanced designs is that the upper frequencyof the IF is dependent upon the quality of the diplexer.Because of the diplexer's filtering it is nearly impossi-ble for the IF to be close in frequency to the RF or LO.

In the early 1980s, a solution to this problem was real-ized using what is commonly referred to as a doubledouble-balanced or triple-balanced mixer design. Inthis approach, an additional microstrip balun and twicethe number of diodes are incorporated to providethree mutually balanced ports on the mixer. With thisapproach, only balance is required to cancel oneport's signal at the other. Therefore, overlapping fre-quencies and microwave IF coverage are no longerproblems.

The triple-balanced mixer is now common up to 26GHz with IF coverage available to 12 and sometimes15 GHz. Irrespective of its near-commodity status, amicrowave triple-balanced mixer is not a simpledevice. This design typically requires three orthogonalmicrostrip baluns with two diode quads soldered to allthree, as shown in Figure 4. The limitation to extend-ing this structure above 26 GHz has been typicallyassociated with the parasitics of the complicateddesign and construction.

FIGURE 4Higher frequency vesions of this same design havebeen developed over the last several years. In 1994,a breakthrough development resulted in the ModelTB0440LW1 4 to 40 GHz triple-balanced mixer.Through reconstruction of the diode structure andtightly controlled manufacturing processes, this newmixer offers what was needed all along to accomplishKa-band block frequency conversion.

BLOCK CONVERTER ASSEMBLY

A long with the development of a high-performancemillimeter-wave mixer, other support products had tobe developed to facilitate this LNB converter, asshown in Figure 5. As with most receivers, sensitivityis a critical electrical specification. To meet thisdemand, the JS series low-noise amplifiers (LNA)operating at frequencies up to 60 GHz were devel-oped. Integrated into the front end of the LNB-2640-40block converter is a 26 to 40 GHz LNA providing 24 dB

unit to unit. The IF band is unfiltered and boosted ingain by a four-stage LNA operating over the 0.5 to 20GHz band. This amplifier not only drives the +10 dBmoutput power, but provides a good broadband matchfor interconnection to existing systems even through along cable run.

SYSTEM-LEVEL PERFORMANCE

A performance summary of the LNB converter’s indi-vidual components and the cumulative receiver is list-ed in Table 1. Table 2 lists some of the mixing spuri-ous signals that can be expected from a -40 dBm inputsignal. In addition to the listed typical performance, avariety of standard options are offered, including anoninverting frequency conversion utilizing low sideLO mixing, WR42 and WR28 waveguide inputs, anexternal LNA for remote feed applications, a lowphase noise LO utilizing dual-loop vs. digitally lockedtechnology and an internal crystal reference with fre-quency stability to ±1 PPM.

The applications realized with these millimeter-waveblock frequency converters span a variety of cus-tomers and markets. Block conversion is a simplesolution to a system option that was often overlookeddue to technical concerns. As technology moves fur-ther into the millimeter-wave bands, block conversionis expected to become a more frequently sought-aftersolution to broadband system problems.

Along with the LNA, a 42 GHz LO is required to facil-

itate the block conversion. A phase-locked ceramicresonator oscillator at 2.8 GHz, digitally locked to anexternal 10 MHz reference, is utilized. This frequencyis then multiplied and filtered to 14 GHz by a singlestep-recovery diode multiplier, and finally multipliedagain to 42 GHz by means of a balanced X3 Schottkydiode multiplier. The multiplied ceramic resonatorapproach was chosen over a phase-locked dielectricresonator oscillator (DRO) at 14 GHz due to the costimpact of utilizing the DRO. Although some size issacrificed, overall manufacturability and performanceare not compromised.

The final 42 GHz LO was chosen based upon thespurious signal performance of high side mixing, aswell as the ease of filtering the image response andLO leakage. With high side mixing, much of the imagesuppression is inherent in the roll-off of the amplifier.However, a multisection waveguide bandpass filter isincluded to ensure consistency in performance from
