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.
