400 MHz Transmit/Receive Front-End Module

The SKY65366-21 is a high-performance, transmit/receive (T/R) range extender. The device provides a complete T/R chain with T/R switches.

The device transmit chain features +30.2 dBm output. The device receive chain features a low-noise amplifier (LNA) with a 1.8 dB noise figure (NF) and 21 dB gain. The cascaded NF and gain, taking into account the 0.4 dB insertion loss transmit/receive antenna switch, are 2.2 dB and 20.6 dB, respectively.

The module also has a shutdown mode, PA bypass mode, and LNA bypass mode to minimize power consumption.

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.
