RF Power Amplifier Modules

Buying guide

Check three hard specifications first: operating band, saturated output power and gain. Then confirm supply voltage, connector type and cooling requirements. Continuous-wave and pulsed duty cycles place different demands on linearity, and long full-power runs need thermal headroom, so add forced-air or liquid cooling where the enclosure is sealed. When paralleling modules, evaluate isolation and combiner loss before finalising the layout. Common bands run from 100 MHz to 5.8 GHz, with 433 MHz, 900 MHz, 1.2 GHz, 1.5 GHz, 2.4 GHz and 5.8 GHz carrying most jammer and counter-UAS work. Typical uses include jammer integration, RF test benches and custom transmitters. Ask for gain curves and power test data with each unit, and confirm the module footprint before designing the enclosure.
