The linearized microwave power module

Abstract

Microwave power modules (MPMs) provide the most compact and efficient source of microwave/millimeter wave amplification in the 50 to 150 W power range. They can also amplify over a multi-octave frequency band. MPMs have been around for almost ten years and applied in military radar and electronic warfare, but have seen little application in communications. This paper shows that by combining an MPM with a linearizer, high power, high efficiency and high linearity can all be achieved. This combination should make linearized MPMs highly attractive for both commercial and military communications applications.
