Abstract

A W-band sub-harmonic mixer was presented employing microstrip hybrid microwave integrated circuit.The parasitic parameter introduced by package structure of the diode was analyzed.Then a method is proposed to reduce the parasitic capacitance of the diode.In order to avoid grounding with via-hole and usage of edge-coupled band-pass filter in the W-band which are commonly encountered in traditional sub-harmonic mixers,a modified configuration of sub-harmonic mixer was proposed.The measured minimum single side conversion loss is 8 dB at a LO of 45 GHz and an IF of 2.4 GHz.The conversion loss is less than 10.5 dB in the range of 90-100 GHz.

利用微带技术设计w波段次谐波混频器
采用微带混合微波集成电路设计了一种w波段次谐波混频器。分析了二极管封装结构引入的寄生参数。然后提出了一种减小二极管寄生电容的方法。针对传统亚谐波混频器存在的过孔接地和w频段使用边耦合带通滤波器等问题,提出了一种改进的亚谐波混频器结构。在本端电压为45 GHz,中频为2.4 GHz时,测量到的最小单侧转换损耗为8db。在90 ~ 100ghz范围内,转换损耗小于10.5 dB。
