Abstract

In this paper the design and the measurement of a 2 GHz 50 Watt (CW) MMIC power amplifier (PA) are discussed. The authors believe that this is the most powerful MMIC implementation that has been reported. The amplifier utilizes a class-F combining structure and realized using the company internal 0.5 /spl mu/m GaAs pHEMT power process. The MMIC measure 10/spl times/10 mm/sup 2/ and delivers 50 Watts of CW power at an efficiency greater than 45% over more than 10% bandwidth at a nominal 12 V supply voltage. The amplifier gain is 21 dB throughout the operational band.

50瓦MMIC功率放大器设计，适用于2 GHz应用

本文讨论了一种2ghz 50瓦(CW) MMIC功率放大器的设计与测量。作者认为这是目前所报道的最强大的MMIC实现。放大器采用f类组合结构，采用公司内部0.5 /spl μ m GaAs pHEMT功率工艺实现。MMIC测量10/spl倍/10 mm/sup 2/，在标称12v电源电压下提供50瓦的连续波功率，效率大于45%，带宽大于10%。放大器在整个操作频带的增益为21 dB。
