摘　　要：利用ADS软件辅助设计一工作在LS波段的微带无源单平衡下变频混频器。介绍了电路的工作原理,ADS仿真设计过程,给出了电路制作版图和测试结果,测试结果和仿真结果吻合,电路具有较低的变频损耗。混频器射频输入信号2440MHz,本振信号为2070MHz,输出中频信号370MHz,变频损耗为9.33dB。This paper present the design of a LS band microstrip-line single-balanced down converter mixer using the tool of ADS. We introduce the principle of the circuit, the process of simulating, the circuit domain and the measured result, the simulated and the measured result are the same, the design with well conversion loss. The signal frequency is 2440MHz, LOF is 2070MHz and the output IF is 370MHz, The measured conversion loss is 9.33 dB.

关 键 词：单平衡混频器 变频损耗 中频信号
