Abstract
This paper introduces the fabrication process and circuit design method for microwave monolithic integrated GaAs PHEMT switches and logic control circuits.Using 0.8μm GaAs E/D PHEMT technology,an integrated SPDT switch MMIC is fabricated.In the DC~10GHz,the insertion loss is less than 1.6dB,and the isolation is greater than 24dB.The logic circuits are integrated with the switch circuit successfully.The whole circuit only needs one control signal for voltage,reducing the port number of control circuit switches and saving chip area.-
