Figure 2 Exploded view of the RF Module (Dual)

The RF Module can support one to three sectors with the following integrated compo-nents:

• Transceivers with TX for two to four carriers (three transceivers in the 3-sector RF Module, two in the Dual and one in the Single RF Module)

• Transceivers with RX for two to four carriers with diversity (the carriers must be adja-cent) (three transceivers in the 3-sector RF Module, two in the Dual and one in the Single RF Module)

• Linear power amplifiers (three in the 3-sector RF Module, two in the Dual and one in the Single RF Module)

• RF filters with main and div branch (three in the 3-sector RF Module, two in the Dual and one in the Single RF Module)

• 48 V DC input power supply • Masthead amplifier and 3GPP Antenna tilt power feed and control for up to three

sectors • Interface to the System Module • Interface for chaining System Modules (3-sector RF Module only) • Integrated fan assembly (two fans) • Full operational bandwidth support

12 DN7085361




• Antenna connector interfaces • Prepared for AISG2.0

The 3-sector RF Module has three independent transceivers each composed of one transmitter chain and two independent uplink chains to implement uplink diversity. The unit integrates an antenna filter unit that contains three filter blocks, each composed of one duplex filter (main antenna) and RX filter (diversity antenna), providing six antenna connectors for the BTS antenna line. The transceivers can be configured independently to dual or single carrier modes.

The Dual RF Module has four dual carrier receivers that facilitate two dual carrier receiv-ers with 2-way uplink diversity and it can therefore support multiple configurations.

The Single RF Module is a half capacity version of the Dual RF Module. It has one TX/RX output that supports a maximum of two TX carriers (two carriers per TX chain). There is one RX output connector as well.

The RF Module uses nominal 48 V DC for internal power supply. The FRGD can also use nominal 100/240 V AC (optional unit), which increases the power consumption by approximately 10 %.

The main and diversity branches include Bias-Ts with lightning strike protectors (Single and Dual RF Module). The main branch (Tx/Rx) Bias-T is used for Flexi Antenna Line and MHA support. It supports Current Window Alarm (CWA) mode, and 3GPP and AISG 2.0 interfaces (the FRGG, FRGF, FRGP, FRGJ, and FRGK also support the proprietary AISG1.1 interface for NBxx replacements). The diversity (Div Rx) branch Bias-T is only used for MHA support in Current Window Alarm (CWA) mode. The main branch also includes an Antenna Line VSWR Monitor (power meter for forward and reflected voltage ratio measuring). The operating voltages fed via main antenna line are 0 V DC/+12 V DC/+28.5 V DC and via diversity antenna line 0 V DC/+12 V DC.

The VSWR monitoring system is used for producing alarms for the antenna line condi-tion against alarm threshold (RRH, Single, Dual and 3-sector RF Module). As a default setting, the minor alarm will be generated when the VSWR is 1.9 and major alarm (cell down) will be generated when the VSWR is 2.6. However, it is possible to adjust both minor and major alarm threshold between 1.5-3.5. The antenna line does not provide any alarms without a valid licence (Line Supervision RAN907LK).

AISG1.1 RET Antenna Line Device configuration is supported with the FRGG, FRGF, FRGP, FRGJ, and FRGK.

Flexi RF Module has 4.2MHz wide filtering in the receiver side. 4.2 MHz filtering reduces uplink interference from adjacent systems (such as GSM) and enables WCDMA deploy-ment in less than 5 MHz in frequency refarming cases. The 4.2 MHz fixed filtering has been implemented in 900 MHz products (WN4.0), 850 MHz products (WN5.0), 1900 products (WN5.0 CD3) and 1800 products (WN6.0).

Functional blocksThe RF Module includes the following functional blocks:

• RF control block: There are interfaces from the RF control block towards the System Module through optical connection. Most unit internal connections are made from the RF control block. Signal processing and unit control functionalities are located in this block.

• TX block: Analogue RF parts are located in the TX block. • PA block: The power amplifier block amplifies TX block output signal to a specified

output power level. • RX block: In dual version, the RX block includes four 2-carrier receivers and in

Single RF Module two 2-carrier receivers. In 3-sector RF Modules, the RX block includes six 4-carrier receivers.

• Antenna filter block: Antenna filtering for TX and RX signals is done in the Antenna filter block.

In the Single version, there is only one TX block, PA block and Antenna filter block. In the RX block, only half of the blocks components are installed.

RF Module versions FRGF, FRGP, FRGJ and FRGK support 2100 MHz band with high gain MHA. The FRGJ and FRGK can be used with NBxx replacements having 24 dB TMA installation, thus existing TMAs can be utilised.

The FRGF, FRGP, FRGJ and FRGK support 2100 MHz band with high gain MHA from 0 dB to 33 dB.

Table 9 Power consumption of the Dual and Single RF Module

DN7085361 25




Maximum power consumption values consist of power feed to MHA + antenna tilt (1x30 W with the Single RF Module, 2x30 W with the Dual and 3x30 W with the 3-sector RF Module). Up to 50 W/100 W/150 W (Single/Dual/3-sector) higher power consumption can exist in extreme conditions and in BTS output power overdrive situations. In possible short-circuit cases (for instance, antenna line) power consumption can momentarily be higher.

g The values are given for the 2.1 GHz radio frequency (RF) module. For other RF module variants, power consumption can increase by a maximum of 10 %.

In case the Single RF Module uses an optional AC power supply (FPAB), the power con-sumption is 10% higher compared to the values in the table above.

Power consumption of the Remote Radio HeadThe table below lists the power consumption of the Remote Radio Head.

In case the Remote Radio Head uses an optional AC power supply, the power consump-tion is 10% higher compared to the values in the table above.

Note that these values are applicable under normal operating conditions, in 1 carrier mode and in middle frequency.

Maximum power con-sumption (Single/Dual in 40W mode and 3-sector in 60W mode) including extreme tem-peratures and power feeding to MHAs and tilting antennas via inte-graded Bias-Ts.
