NOKIA FHDB 472649A 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.
Flexi Multiradio BTS GSM/EDGE modules are equipped with an integrated air guide plate providing full thermal compliance without casings. This allows installation of the modules without casings in Flexi cabinets and enclosed 19″ racks. Casings and covers are recommended in standalone 19″ racks (no cabinet) for safety reasons. Casings are not part of the FXxx delivery package. If the configuration requires casings, Flexi BTS Module Casing (EMHA) kits must be ordered.
