Flexi RF Module Triple (FXxx)

The Flexi Multiradio Radio Frequency Module (FXxx) or RF Module, is a 3-branch multicarrier,multi-standard radio transceiver module. The module consists of three independent branches, capable of transmitting and receiving signals of multiple radio technologies concurrently:

• Up to 6 GSM carriers with 400 KHz minimum carrier separation
• Up to 4 WCDMA carriers with 4.6 MHz minimum carrier separation
• Multi-carrier LTE signal with 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, and 35 MHz carrier bandwidth
• Multi RAT operation with combination of GSM, WCDMA, and LTE

The RF Modules FXDA, FXDJ, FXEA, FXCA, and FXFA/ FXFB are referred to as 70W RF Module variants. RF Modules FXEB and FXDB are referred to as 90 W RF Module variants. Each branch consists of a transmitter and two receiver chains. FXxA and FXFB (70W) variants have front end software tunable filters (STuF). 90 W RF Module variants have fixed full band filters. FXxx is a 3U high module with an integrated, replaceable 3-fan assembly for module cooling. The supported functions are:

• Chaining up to three RF Modules with OBSAI RP3_01
• 2-way receive diversity in the receiver chains
• Integrated antenna line supervision
