DC TO 20GHz SPDT pHEMT GaAs SWITCH

RFMD’s RFSW2043 is a broadband absorptive SPDT GaAs microwave monolithic

integrated circuit (MMIC) switch designed to operate from DC to 20GHz using the

RFMD FD05 0.5μm switch process. It features low insertion loss of 2.25dB at

20GHz and high isolation of 26dB at 20GHz while being packaged in a compact

low cost 3mmx3mm QFN package for easy end use assembly. The switch uses

complementary control logic of -5/0V and does not require a separate bias supply.
