A Kind of GaAs Microwave PIN Diode with the Improved Structure

Haiying Zhang

Abstract

A kind of high performance GaAs microwave PIN diode was designed and fabricated.The relationship between the performance and the structure of GaAs PIN diode is analyzed.An improved structure of GaAs PIN diode is present.GaAs PIN diodes with different structures are fabricated,testing data of PIN diodes with usual and improved structures are compared,and the results of analysis in theory are proved.The improved GaAs PIN diodes are easier to fabricate,and has better high frequency performance.The cut-off frequency of this kind of diode achieves 1 520.5 GHz.This kind of diode could be applied in microwave circuits.
