Skyworks Solutions, Inc. 900 MHz Transmit/Receive Front-end Module SKY65346-21

Please note: SKY65346-21 is being discontinued and is not recommended for new designs. The SKY65346-21 is a high performance transmit/receive (T/R) Front-End Module (FEM) ideally suited for use in 900 MHz Industrial, Scientific, and Medical (ISM) applications. A double-pole, double-throw (DPDT) switch allows the device to select between two antenna ports (ANT1 and ANT2 pins) for the transmit or receive path. A single-pole, double-throw (SPDT) switch selects which signal path is routed to the transceiver port (RFIO pin). The receive path has a Low-Noise Amplifier (LNA) bypass switch. The Power Amplifier (PA) and LNA biasing can be independently controlled with an external bias resistor. The device has a shutdown mode to minimize power consumption. All eight operating modes are controlled using three digital input pins (CTL1, CTL2, and CTL3). The SKY65346-21 T/R FEM is provided in a compact, 26-pin 5 x 5 mm Multi-Chip Module (MCM).
