An 8~20GHz Monolithic SPDT GaAs pin Diode Switch
-
Abstract
Monolithic GaAs pin diode single pole double throw (SPDT) switches based on the fabrication technology of IMECAS are designed,fabricated,and tested.These SPDT switches achieve an insertion loss of 1.5dB,isolation of 32dB,and input and output return losses over 10dB from 8 to 20GHz.The switch design uses 2.5μm thick I-region GaAs pin diodes and a series-shunt-shunt switch topology in each arm.These performance characteristics are measured at a normal bias setting of 1.3V,which corresponds to 7mA of series diode bias current.-
