Abstract :
This paper presents a new predistortion technique using GaAs dual-gate MESFETs to linearize the microwave power amplifiers. The results of a linearized 16-watt traveling wave tube amplifier at 12 GHz are presented. The linearize affects a 12 dB reduction in this third-order intermodulation products at 2.5 dB input power back off.
