Product Description
Features
The RF3021 is a high isolation single-pole double-throw (SPDT) reflective
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 3V. This GaAs pHEMT switch is housed in
a compact 3mm, 16-pin, leadless QFN package.
