摘要

提出了一种工作频率为1.8 ~ 4.0 GHz的7w GaN HEMT自适应功率放大器(APA)。为了控制APA状态，在输入和输出匹配网络中都使用了六个引脚二极管作为调节器。该设计基于小信号方法建模有源元件，如晶体管和调节器。APA的测量结果证明了所提出的设计方法的有效性。APA由专门的单元——通用自适应控制器控制。

A S-band 7 W GaN HEMT adaptive power amplifier

In the paper a 7 W GaN HEMT adaptive power amplifier (APA) operating over 1.8 to 4.0 GHz is presented. To control APA states the six pin diodes as regulators have been used in both input and output matching networks. The design is based on the small-signal approach for modelling active elements such as transistor and regulators. The measured results of APA have proven usefulness of the proposed design methodology. The APA is controlled by specialized unit - Universal Controller of Adaptation.
