基于新颖宽带肖特基二极管模型的毫米波平衡式混频器设计
Millimeter-wave balanced mixer based on a novel wide-band Schottky diode model
摘要
Abstract
A Schottky diode model for the mixer' s design is presented in this paper.According to the physical structure of the Schottky diode,a novel 3D electromagnetic (EM) model was built and analyzed by finite element method.A wide-band equivalent circuit up to 110 GHz was proposed taking the parasitic effects distributed in the diode into account.Based on the proposed equivalent circuit,a Ka-band balanced mixer was designed and optimized.The measured conversion loss is 7.5 dB to 10 dB from 32 GHz to 37 GHz,which agreed well with the simulated one.关键词
