RF3025

SPDT, HIGH ISOLATION, SINGLE CONTROL,

ABSORPTIVE SWITCH

The RF3025 is a high isolation single-pole double-throw (SPDT) absorptive

switch designed for general purpose switching applications requirinng

moderate insertion loss and power handling capability. It features single-

bit control with operation as low as 3V. This GaAs pHEMT switch is housed

in a compact 3mm, 16-pin, leadless QFN package.
