450 MHz Transmit/Receive Front-End Module

The SKY65377-11 is a high-performance, transmit/receive (T/R) front-end module (FEM). The device provides a complete T/R chain with T/R switches.

The device transmit chain features +30 dBm output power and a 40 percent Power Added Efficiency (PAE). The module also has a shutdown mode.

The device is mounted in a 28-pin, 6 x 6 mm Multi-Chip Module (MCM) surface-mount technology (SMT) package, which allows for a highly manufacturable low-cost solution.

Please note: SKY65377-11 is being discontinued and is not recommended for new designs. The suggested replacement is SKY65377-21.
