Description

The F2977 is a 50

single-pole double-throw (SP2T) reflective RF

switch featuring high linearity and wide bandwidth. This device is

optimized from 30MHz to 6GHz to support a multitude of wireless

RF applications. The F2977 uses a single positive supply voltage

of either +3.3V or +5.0V and is compatible with either 1.8V or 3.3V

control logic.

Competitive Advantage

The F2977 provides extremely low insertion loss across the entire

bandwidth while providing superb distortion performance.

Low insertion loss

High isolation

Low distortion

Fast switching

No external matching required
