本文采用UMS公司的DBES105a型号的反向并联肖基特势垒混频二极管管对，设计了一种E波段低变频损耗八次谐波混频器，该混频器主要由射频输入端的波导-微带过渡、混频反向二极管对、开短路短截线、中频滤波器以及各端口匹配网络组成。在射频输入端采用低插入损耗的波导-鳍线-微带过渡，在中频输出端，采用一种新型紧凑微带谐振单元（CMRC）结构来设计中频输出滤波器。通过优化匹配电路等结构参数，仿真结果表明在60-90GHz范围内，变频损耗低于24dB，最低变频损耗18.9dB。

In this paper, a E-band low conversion loss eighth subharmonic (SH) mixer is designed. Antiparallel Schottky barrier mixer diode pair DBES105a is adopted in the SH mixer.the subharmonic mixer consists of waveguide to microstrip transition,anti-parallel diode pair,IF low pass filter and matching network of every port.The RF signals are introduced by low insertion loss waveguide-finline-microstrip transition and the IF signals are fed out by a novel Compact Microstrip Resonating Cells (CMRC) filter. By optimizing the structural parameters of input and output matching networks, the conversion loss in the band of 60GHz~90GHz is less than 24dB, and the minimum is 18.9dB.
