Abstract

This paper presents the design of a concurrent tri-band Doherty Power Amplifier (DPA) for 1.84 GHz, 2.14 GHz and 2.65 GHz frequency bands. The frequency response around each operating band is maximally flattened adopting a new design strategy. The DPA is based on hybrid technology using two 8 W GaN HEMT as active devices. The results show a peak of drain efficiency higher than 60 % in each operating band and over 45 % at the corresponding 6 dB output power back-off (OBO). Finally, more than 200 MHz of bandwidth is achieved around each operating frequency.

并发三频带多尔蒂功率放大器的设计方法

本文设计了一种用于1.84 GHz、2.14 GHz和2.65 GHz频段的并发三频带Doherty功率放大器(DPA)。采用新的设计策略，每个工作频带周围的频率响应最大程度地平坦化。DPA基于混合技术，使用两个8w GaN HEMT作为有源器件。结果表明，在每个工作频带，漏极效率峰值均高于60%，在相应的6 dB输出功率回退(OBO)时，漏极效率峰值超过45%。最后，在每个工作频率周围实现了200 MHz以上的带宽。
