1 RF Module and Remote Radio Headoperation and main blocks
The RF Module and Remote Radio Head (RRH) are stand-alone fullyoperational transceiver modules with integrated antenna filters. The RF
Module is able to support one to three sectors, whereas the RRH supports
one sector in a Flexi WCDMA base station. The RF Module and RRH host
the RF functionality and provide control and power supply to the Flexi
Antenna Line. Radio-related signal processing is performed in the RF
Module. The RF Module has integrated fans and Bias-Ts. The RRH does
not have any fans.
There are three types of RF Modules available:
.
Triple RF Module
. Dual RF Module
. Single RF Module
For detailed information on delivery contents, see Contents of the RF
Module Deliveryin the Installing Flexi WCDMA BTS Modules for Stack,
Wall, and Pole Configurationsdocument.
Caution
Incorrect cables and seals may not provide secured weather protection.
In outdoor installations, including the outdoor cabinet, use only tested,
at least IP55 class outdoor antenna jumper cables provided by NokiaSiemens Networks. This is also recommended for indoor installations.
The following versions of the RF Module and Remote Radio Head are
available:

. Transceivers with TX for two carriers (three transceivers in the Triple
RF Module, two in the Dual and one in the Single RF Module). Transceivers with RX for two carriers with diversity (the carriers must
be adjacent) (three transceivers in the Triple RF Module, two in theDual and one in the Single RF Module)
. Linear power amplifiers (three in the Triple RF Module, two in the
Dual and one in the Single RF Module)
. RF filters with main and div branch (three in the Triple 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 (Triple RF Module only)
. Integrated fan assembly (two fans)
. Full operational bandwidth support
. Antenna connector interfaces
.
Prepared for AISG2.0
The Triple 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 supportmultiple 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-Tis used for Flexi Antenna Line and MHA support. It supports Current
Window Alarm (CWA) mode, and 3GPP and AISG 2.0 interfaces (the
FRGJ and FRGK also support the proprietary AISG 1.1 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 andTriple 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, FRGJ, and FRGK.

The functionality of the RRH is similar to the functionality of the Single RF
Module with the exception that the RRH does not have any fans. The RRHsupports the VSWR monitoring system and is AISG2.0 compatible. The
RRH has one TX output that supports a maximum of two TX carriers (two
carriers per TX chain). See the numbers of RF connectors and carriers in
the following table.
Table 3. Remote Radio Head RF connectors and number of carriers

# TX/RX connectors 1
# RX connectors 1
# carriers 2 (3 HW prepared)
Functional blocks
The RF Module and RRH include 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.
. 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 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 FRGJ and FRGK support 2100 MHz band with high gain MHA from 0
dB to 33 dB.

6 RF Module and Remote Radio Head LEDindications
The RF Module and Remote Radio Head have two LEDs on the frontpanel to indicate the operational status of the module and all fault
conditions during operation. Read the information on LED indications
thoroughly. A blinking red LED does not always require removing the
module.
RF Module LED indications
The RF Module LEDs are as follows:
. one for the RF core functional block
. one for the fans in the RF Module
The LED indications of the RF Module are listed and explained in the
tables below.
