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).
