High Linearity Broadband SP2T

5MHz to 10GHz

F2972

Datasheet

Description

Features (75ꢀ)

The F2972 is a singleꢀpole doubleꢀthrow (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 50ꢁ or 75ꢁ

terminating impedance applications.

ꢀ

Low insertion loss:

ꢀ

0.23dB at 204MHz

0.34dB at 1.8GHz

ꢀ

High Isolation: 40dB at 1.8GHz

P0.1dB compression of +37dBm at 204MHz

Second Harmonic: ꢀ100dBc at 204MHz

Third Harmonic: ꢀ120dBc at 204MHz

Composite Second Order Distortion > 100dBc

Composite Triple Beat Distortion > 100dBc

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.
