Design and fabrication of a 2 mm-band sub-harmonic mixer based on quartz
摘要
介绍了一种基于石英基片的2mm波段二次谐波混频器.阐述了谐波混频器的基本原理, 建立了混频二极管对结构的高频模型, 并用全波分析软件对整个电路进行了仿真优化.实测得到射频信号在116~120GHz范围内, 当本振频率为59GHz、功率为7~14dBm时, 最低变频损耗为17dB, 最高变频损耗为20dB.混频器的P1dB为1dBm, 各端口隔离度均优于20dB.研制的集成2mm波段二次谐波混频器实测结果与设计结果吻合较好.
Abstract
An integrated 2mm band sub-harmonic mixer based on quartz circuits was presented. General harmonic mixer theory was introduced. The equivalent circuit model for the anti-pair diodes was built. Then the extensive simulation and optimization by the full wave analysis software were done. When the 59GHz LO signal’s power was set between 7~14dBm, the mixer yielded a least conversion loss of 17dB and a maximum loss less than 20dB under working frequency of 116~120GHz. The P1dB of the mixer is about 1dBm. The isolation between the three ports is better than 20dB.The measured results of the sub-harmonic mixer are agreed well with the simulated ones.
