Designed for high efficiency (better than 14% DC-to-RF efficiency), model BME69188-50 is a broadband power amplifier (PA) module capable of 50 W output power from 6 to 18 GHz. Based on gallium-nitride (GaN) active device technology, the Class-AB linear PA module delivers 47 dB gain with +/-4 dB gain flatness across the full frequency range. The input overdrive level is +10 dBm. The maximum input/output VSWR is 2.0:1. Spectral purity is excellent, with second harmonics of -15 dBc, third harmonics of -25 dBc, and spurious levels of -60 dBc. Suitable for boosting signals in communications, electronic-warfare (EW), and radar systems, the PA module features built-in test functions, including over temperature, over current, and composite test capabilities. It runs on a +28-V dc supply and has TTL-controlled enable/disable function with 1-μs switching speed. The amplifier measures 6.56 x 3.50 x 0.84 in. and weighs 1.5 lb. with field-replaceable female SMA RF input and output connectors. It handles operating temperatures from -40 to +55°C.
