准单片连续B/J类Doherty功率放大器研制
Journal of Microwaves（2023）
Abstract
文中采用准单片工艺研制了两级连续B/J类Doherty功率放大器.采用非对称Doherty架构,分析当载波功放的阻抗逆变网络出现失配时,峰值功放非无穷输出阻抗对载波功放负载的影响,扩展了连续B/J类Doherty功放的阻抗设计空间,在保持高回退效率的同时拓展带宽.该设计方法无需提取管芯的封装参数,摆脱对特定管芯的依赖,更具有普遍性.测试结果表明,采用准单片工艺的2.3～2.7 GHz频段连续B/J类Doherty功率放大器输出功率大于35 dBm,回退8 dB漏极效率大于36％.
