RF3021
SPDT, HIGH ISOLATION, SINGLE BIT CONTROL, SWITCH
Package: QFN, 16-Pin, 3 mm x 3 mm
Product Description
The RF3021 is a high isolation single-pole double-throw (SPDT) switch designed for general purpose switching applications requiring moderate insertion loss and power handling capability. It features single-bit control with operation as low as 3 V. This GaAs pHEMT switch is housed in a compact 3 mm, 16-pin, leadless QFN package.
