Lorch Microwave’s MP-Series, Manual Phase Shifters, are
mechanically variable devices offering a continuously vari-
able phase shift over a 0-90 or 0-180 degree range. These
devices use a lumped element quadrature hybrid along
with a pair of matched variable LC networks. The LC net-
works are tied to ports 2 and 3 of the quad hybrid (See
Figure 1) to form a “sliding” short. These elements, when
placed at the output ports of the hybrid, will reflect inci-
dent energy back into the hybrid. The reflected energy
then appears at port 4, the isolated port. As the LC ele-
ments are varied, the apparent distance (or electrical
length) of the sliding short, changes the phase angle of the
reflected signal.
The phase adjustment is via a 34 turn mechanically vari-
able capacitor. Phase shift verses number of turns is shown
in Figure 2.
Notes:
1) All units rated at 0.5 Watts Avg, 2 Watts Peak. The Peak/Average power handling capacity applies for thru-line VSWR’s of1.25:1 max.
The units listed are designed to provide optimum performance over thefull 10% bandwidth. If the band of interest is narrower than listed, itshould be indicated when ordering (See “Creating a Part Number”).Performance will be optimized over the band of interest and improvedperformance may be offered at no extra cost.

Lorch Microwave’s VP-Series, Voltage Controlled Phase
Shifters, are wideband miniature components available in
a wide range of center frequencies and bandwidths.
Standard models are available with 0-90°, 0-180° and
0-360° continuously adjustable phase range. These devices
use voltage variable capacitors (varactor diodes) to achieve
the desired phase shift.

Applications
Definition of TermsPhase ShiftThe minimum total phase shift in degrees occurring when
control voltage is varied from minimum (0 VDC) to maxi-
mum. For standard models the phase shift is positive.
Insertion PhaseThe difference in phase between input and output ports as
the device is inserted in line with the control voltage set at
0 volts.
Control VoltageThe DC voltage range required to shift the phase from the
minimum to the maximum specified amounts.
DescriptionLorch Microwave’s VP-Series Phase Shifters are voltage
variable devices offering a continuously variable phase
shift over a 0-90, 0-180 or 0-360 degree range. Phase con-
trol is achieved by the application of a control signal. The
control voltage varies the capacitance of two matched var-
actor diodes which form LC resonant circuits connected to
the output ports of a 90 degree Hybrid. The change in
diode reactance causes a shift in phase of the RF signal.

Digital Phase Shifters
❚ 1-1000 MHz frequency range
❚ Up to a full octave bandwidth
❚ 0-360 Degrees phase shift
❚ Integral TTL driver
❚ 1-8 bit control
❚ Accuracy to 1⁄2 least significant bit
❚ Time shifter or frequencyindependence
Lorch Microwave’s DP Series, Digital Phase Shifters,
are available for frequencies from 1 to 1000 MHz. These
phase shifters are composed of high performance GaAs
switches that have little power consumption, fast switch-
ing time, and extremely low switching transients.
All units are TTL compatible, with one control line per
bit. TTL high voltage state corresponds to zero phase
shift on standard units, but reversed logic may be
obtained if required. As a convention, all phase shifts are
negative.
Description
Figure 1 illustrates three distinct types of phase shifters,
namely: Type 1 (Phase Shifter), Type 2 (Time Shifter),
and Type 3 (Phase Inverter). They have quite different
performance characteristics, proper selection is gov-
erned by consideration of the system in which the shifter
is to be used.
Type 1 (Phase Shifter) uses special networks to obtain
any desired phase shift, shown as 0 degrees, 90 degrees
and 180 degrees in the example of Figure 1A. The 90
degree and 180 degree shifts have phase/frequency
slopes parallel to that of the initial insertion phase char-
acteristic, signifying constant time delay. The Type 1
Phase Shifter changes the phase of the incoming signal
while maintaining constant time delay, or group delay.
The delay is that of the initial insertion phase character-
istic. At all settings, the absolute insertion phase is pro-
portional to frequency, depending on the value of the
insertion delay, but the phase shift is not. This type of
device is inherently narrowband in nature. Wider band-
widths are obtainable, but at a higher cost because of
the complex networks required. Type 1 shifters should
be used only where special characteristics of constant
delay and frequency independent phase shift are
required.

Type 2 (Time Shifter) is illustrated in Figure 1B, which
shows two sections, each with a ‘thru’ path of length lo
and a ‘line’ path of length l1 and l2. The length l2 is
assumed to be longer than l1. It is seen that the insertion
phase of the path l0 is linear with frequency, having a
slight slope, and curve l2 is steeper yet. Type 2 is a true
time shifter compared to the Type 1 Phase Shifter. The
phase characteristic is proportional to frequency at any
phase setting, with a slope proportional to frequency at
any phase setting. Group delay is constant for each
phase setting but proportional to phase shift as the set-
ting is changed. The zero degree phase setting corre-
sponds to the insertion phase, or delay; all other delays
are longer in time. The Type 2 device has an inherently
wide bandwidth, limited only by the switching circuits
used. Type 2 shifters are less expensive than Type 1, have
wider bandwidths with good transient response. They
are recommended for most applications, particularly
those in which time is in fact the variable desired, such
as antenna beam formers.
Type 3 (Phase Inverter) of Figure 1C is a special case and
consists of a simple phase-reversing transformer. It pro-
vides only two possible phase states, namely the inser-
tion phase, 0 degrees and 180 degrees. The phase/fre-
quency slope, or time delay, is approximately the same
for each state. The device exhibits wide bandwidth and
excellent transient response. It has limited applications,
and is the simplest and least expensive.

Press to return to Contents
Phase Shifters of Type 1 and Type 2 can be arranged to
give identical phase shift at a single frequency, e.g. f0 in
Figure 1. It is when the frequency is varied that the dif-
ference between these two types becomes apparent. In
the case of Type 2, (Time Shifter), performance should
be specified in units of time delay. Common usage, how-
ever dictates the specifications of degrees of phase shift
at a given frequency. Only at that frequency will the
device meet the phase specifications. In many instances,
the frequency will be at the center of the bandwidth
specified. To resolve this difficulty, a ‘datum’ frequency is
given in each case, that being the frequency at which the
specified phase shifts occur.
This catalog covers TTL compatible digital phase shifters
comprising of one or several shifters, usually in a binary
sequence as shown in Figure 2. In that example, six sec-
tions are arranged in the sequence 5.625 degrees, 11.25
degrees, 22.5 degrees etc., with a total phase shift of
354.375 degrees, the next step returning to 0 degrees.
Thus a complete 360 degree of phase variation is
obtained, in nominal steps of 5.625 degrees. For conven-
ience, the nominal phase angles are rounded to one dec-
imal place, e.g. 5.6 degrees and 354.4 degrees, etc. Other
sequences and step sizes are available.

outputs can be used to form an unambiguous 360 degree
visual phase indication by observation of a moving dot on
an oscilloscope.
The angular position of the dot is a measure of the angular
difference between the inputs. Arithmetical division of the
sine and cosine outputs gives the tangent of the angular
difference. This technique is particularly useful for provid-
ing extended linear range for phase discrimination in
phase-locked loop circuits.

❚ Phase detection in phase-locked loops
❚ Resolution of complex signals forpresentation in polar form
❚ AGC sensing in phase-lock receivers
❚ Phase demodulation for group delaymeasurements
❚ Comparison of received phase differencebetween antenna outputs in directionfinding systems

Lorch Microwave’s CP-Series, Phase Comparators, con-
sists of interconnected mixers, quadrature hybrid, power
divider and diplexers. These components are especially
designed for low intermodulation distortion and VSWR
characteristics. Figure 2 shows the basic schematic for a
Phase Comparator.
Definition of Terms
Phase ErrorThe DC output voltages, X and Y, are proportional to the
cos(Ø) and sin(Ø) respectively. To obtain the value Ø,
output voltages X and Y are measured and Ø is
computed from:
Measured Ø = tan-1
(Y/X). The phase error is thus defined
as: Phase Error = Actual Ø-tan-1
(Y/X).
Peak Phase ErrorThe phase error of a given comparator has peak values
which occur at a few phase difference points. These
are stable and repeatable and can be reduced by
system calibration.
Zero Crossing ErrorThe indicated phase difference when the actual input
phase difference is exactly 0 degrees.
DC Offset VoltageThe DC video output voltage across 50 Ohms occurring
with only the reference input (Port LO) energized.
Phase Comparators
Low-Level Comparators
Lorch Microwave’s CP-13 Series, Low-Level Phase
Comparators, are designed to accept RF input signal lev-
els of up to +3 dBm.

Lorch Microwave’s MA-Series, Manual Attenuators, are
miniature components which may be adjusted manually
by mechanical rotation to provide a useful range of smoothly
variable attenuation over the frequency range DC to 400
MHz, with low VSWR and low minimum insertion loss.
These manual attenuators are ideal for applications where
the gain of one or more channels must be set or equalized
with precision. Styles 60 and 62 are packaged with pins for
PC board mounting, the control shaft being equipped with
a screw driver slot and restrained by a shaft locking device.
The style 61 and 63 packages have RF connectors and are
provided with a screw driver adjustment.
Package styles 60 and 62 are intended primarily for chassis
mounting within equipment where an initial setting will
remain untouched except for an occasional readjustment.
Package styles 61 and 63 are used in applications requiring
frequent manual adjustment, for example when they are
front panel mounted.
These attenuators use resistive network elements and thus
cause no signal distortion. They are carefully compensated
for side bandwidth and are highly stable with time, humid-
ity and temperature. They will remain at a preset attenua-
tion value for a long period of time.
