摘要

This paper presents the design and performance of a 94 GHz crossbar mixer using chip diodes in crossbar configuration. The mixer has been designed in suspended stripline configuration on 2 mil fused quartz substrate. Co-simulation between Agilent Advance Design System (ADS) and CST Microwave studio is used to simulate and optimize the mixer circuit. The conversion loss of this crossbar mixer with ~10 dBm of LO power over RF bandwidth (89 to 93.8 GHz) with LO frequency at 94 GHz has been measured. Measurement results show minimum conversion loss of the order of 8 dB and achieved LO to RF isolation was greater than 26 dB.
