Design of a 0.01∼67GHz broadband coaxial detector

Abstract

A broadband detector designed for operation from 10MHz to 67GHz based on zero-bias low barrier Schottky diodes is presented in this paper. Accurate design and electromagnetic co-simulation technology are used in ultra-broadband circuit matching optimization to obtain excellent port match and good frequency response. Simulation and measured results of the broadband coaxial detector are given. The measured results show that RF port SWR is less than 1.8; measured sensitivity is 1300 mV/mW typically in the whole frequency band and near 1850mV/mW at 34GHz.
