Datasheet
Description
The F2970 is a high reliability, low insertion loss, 75 Ω absorptive
SP2T RF switch designed for a multitude of cable systems and
other RF applications. This device covers a broad frequency
range from 5 MHz to 3000 MHz. In addition to providing low
insertion loss, the F2970 also delivers excellent linearity and
isolation performance while providing a 75 Ω termination for the
unselected port.
The F2970 uses a single positive supply voltage and supports
3.3 V logic.
Competitive Advantage
The F2970 provides broadband RF performance to support the
CATV market along with high power handling, and high isolation.
