摘　　要：为了设计X频段连续波输出功率大于1 000 W的固态功放,本文采用芯片-功率单元-插箱-系统的合成方法,实现了一种工作于7.14～7.24 GHz,最大输出功率为1 226 W的连续波固态功放系统。方案内关键功率单元采用模块化设计,插箱设计采用了灵活的散热技术和幅相调节技术,最终用8个180 W插箱经过波导魔T三级合成,研制出最大输出功率1 266 W,最大合成效率85.1%,增益大于72 dB,输出1 dB压缩点超过1 100 W的固态功放系统。In order to fulfill a 1000W CW solid state amplifier working in X band, a chip-modle-unit-system combination method was used to realizea systemwith maximum output power of 1 226 Wworkingin 7.14-7.24 GHz.The key power unit was modeled and flexible cooling down technology and amplitude-phaseadjusting technology were used.7 magic T were used to fulfill power combination. Test resultsshowed the maximum output power was 1 266 Wand the combination efficiency was 85.1%. The gain ofthe system was 72 dB and OP1 dB was more than 1 100 W.
