Overview
Brand: Nokia
Product Number: 472084A
Model: FXEA
Discription: NSN Flexi Multiradio RF Module 472084A FXEA (1800MHz 18TRX); GSM 1800 70W
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
-
