900 MHz Transmit/Receive Front-end Module

Skyworks SKY65313-21 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 +30.5 dBm output power and a 40 percent Power Added Efficiency (PAE).

The device receive chain features a Low Noise Amplifier (LNA) with a 1.4 dB Noise Figure (NF) and 16.6 dB gain. The cascaded NF and gain, taking into account the 0.5 dB insertion loss transmit/receive antenna switch, are 1.9 dB and 16.1 dB, respectively, which makes the SKY65313-21 ideal for medium power microwave links such as 900 MHz Industrial, Scientific and Medical (ISM) band applications.

The module also has a shut-down 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-Mounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution.
