介绍了一种用于220 GHz无线通信的带次谐波泵浦的频率上、下变频器的设计和制作。该转换电路基于倒装在悬置石英微带线上的砷化镓肖特基势垒二极管。仿真结果表明，该电路在较宽的频率范围内具有较好的转换损耗。初步测试表明，该下变频器具有良好的转换损耗和噪声性能，最小双边带(DSB)转换损耗为6.5dB，噪声温度为1310K。
The paper presents the design and fabrication of a frequency up- and down-converter with subharmonic pump for wireless communication at 220GHz. The converter circuit is based on GaAs Schottky barrier diodes flip-chipped onto a suspended quartz microstrip line. The simulated performance of the circuit exhibits a good conversion loss over a wide frequency range. The preliminary measurement for the down converter application shows good conversion loss and noise performance, with minimum double side band (DSB) conversion loss of 6.5dB and noise temperature of 1310K.
