RF Module operation and main blocks
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 receivers 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 condition against alarm threshold (RRH, Single, Dual and 3-sector RF Module). As a default
setting, the major alarm will be generated when the VSWR is 1.9 and critical 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 deployment 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 blocks
The 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.
See the following figures for the functional blocks of the RF Module.

Power consumption of the Dual and Single RF Module (Cont.)
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.

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 consumption is 10% higher compared to the values in the table above.
Power consumption of the Remote Radio Head
The table below lists the power consumption of the Remote Radio Head.
