A C-Band Monolithic GaAs PIN Diode SPST Switch
C波段GaAs PIN二极管单片单刀单掷开关

A monolithic single pole single throw (SPST) switch is developed with GaAs PIN diode technology from IMECAS.A novel small signal model of a GaAs PIN diode is developed for circuit simulation.The switch features an on-state insertion loss of less than 1.6dB and a return loss of greater than 10dB while maintaining an off-state isolation of greater than 23dB from 5.5 to 7.5GHz.The measured 1dB power gain compression point is about 20dBm.
