摘　　要：介绍了Ku频段接收前端的高本振抑制设计方法。归纳并分析了高频本振信号的泄露途径,针对性地进行相应的电路和结构优化设计,实现了对泄露信号的高抑制度。最终研制完成的Ku频段接收前端对本振泄漏信号的抑制度最大达到96 dBc。5套样机的测试结果验证了分析与设计的有效性。The design of high LO - rejection for Ku band receiver front - end is described. The leakage approach of high frequency LO signal is summarized and analysed. Corresponding designs of structure and circuits are optimized and high rejection of leakage signal is realized. The max value of LO - rejection of the developed Ku band receiver front - end is 96 dBc. The test results of 5 samples indicate the effectiveness of analysis and design.
