F2972
Datasheet
Description
The F2972 is a single-pole double-throw (SP2T) reflective RF
switch featuring high linearity and wide bandwidth. This device is
optimized from 5MHz to 1.8GHz to support downstream cable
modem future migration for DOCSIS 3.1 applications, and operates
at up to 10GHz to support a multitude of wireless RF applications.
Superb performance is achieved when used in either 50Ω or 75Ω
terminating impedance applications.
The F2972 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 F2972 provides extremely low insertion loss across the entire
bandwidth while providing superb distortion performance.
Optimized for DOCSIS 3.1 applications up to 1.8GHz
Optimized for Wi-Fi applications up to 5.9GHz
Low insertion loss
High isolation
Fast switching
No external matching required
Typical Applications
