摘要

提出了一种适用于Ku/ k波段的超小型MMIC高功率放大器(HPA)，其连续输出功率为6W，增益为23dB，功率附加效率为30%。它采用低成本，商用0.25um pHEMT工艺生产。该MMIC由三级pHEMT组成，芯片尺寸为3.5 /spl倍/ 3.0 mm/sup /。HPA每1毫米/sup 2/芯片面积可实现570mw输出功率。这个值是迄今为止报道的Ku/K/ ka波段的最高功率密度。

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

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.
