Skyworks High-Performance Transmit/Receive
Front-End Modules

Skyworks SKY65337-11 and SKY65346-11 are high-performance transmit/receive front-end modules (FEMs). Skyworks SKY65337-11 is a high-efficiency FEM for ZigBee and other 2.4 GHz ISM band applications. The small 8 x 8 mm multi-chip module (MCM) contains a 2400-2500 MHz high-efficiency transmit path and a low-loss bidirectional path. The bidirectional path can be used to directly connect the antenna port to a directional RF port. SKY65346-11 high-performance FEM is ideally suited for use in 900MHz SM applications. A double-pole, double-throw (DPDT) switch allows the device to select between two antenna ports for the transmit or receive path. A single-pole, double-throw (SPDT) switch selects which signal path is routed to the transceiver port. The receive path has a Low-Noise Amplifier bypass switch.
