A high power density, 6W MMIC for Ku/K-Band applications

Abstract

A Ku/K-Band very small size MMIC high power amplifier (HPA) providing 6W of CW output power, 23dB of gain and 30% power added efficiency for application in the Ku/K-Band is presented. It is produced on a low cost, commercially available 0.25um pHEMT process. This MMIC is composed of three stage pHEMT and chip size is 3.5 /spl times/ 3.0 mm/sup 2/. The HPA achieved 570 mW output power per 1 mm/sup 2/ die area. This value is the highest power density at Ku/K/Ka-Band reported to date.
