RF Module operation and main blocks

1 RF Module operation and main blocks The 3-sector RF Module is a stand-alone fully operational transceiver module with integrated antenna filters. The RF Module is able to support one to three sectors in a Flexi Multiradio base station. The RF Module hosts the RF functionality and provides 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.

f 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 Nokia Siemens Networks. This is also recommended for indoor installations. The following versions of the RF Module are available Flexi Multiradio BTS LTE: Version

DN0951745



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 RF Module uses nominal 48 V DC for internal power supply. In case AISG2.0 is used the following versions of RF Modules use 12 V DC only: • • • • •

FRIE Core version A101 FRGP Core version A101 FXEA version A101 FXFA version A101 FXDA version A101

The VSWR monitoring system is used for producing alarms for the antenna line condition against alarm threshold (RRH 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. In terms of H-type configuration the main and diversity branches are reversed for the middle sector (sector 2).
