SKY65313-21 is a high performance transmit/receive (T/R) front-end module (FEM). The device transmit chain features +30dBm output power and 40 percent power added efficiency (PAE), while the device receive chain contains 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 T/R antenna switch, are 1.9 dB and 16.1 dB respectively – making the FEM ideal for medium power microwave links such as 900 MHz ISM band applications. The 28-pin, 6 x 6 x 0.9 millimeter (mm) device, packaged in a multi-chip module, surface-mounted technology unit, also has a shut-down mode and LNA bypass mode to minimize power consumption – allowing for a highly manufacturable, low cost solution.
