            F2972 and F2976 SPDT Reflective RF Switches
                    Renesas offers the F2972 and F2976 SPDT reflective RF switches with wide frequency range, low distortion, and low insertion loss
    

Renesas’ F2972 and F2976 are single-pole double-throw (SP2T) reflective RF switches featuring high linearity and wide bandwidth. These devices are optimized from 5 MHz to 1.8 GHz to support downstream cable modem future migration for DOCSIS 3.1 applications, and operate at up to 10 GHz to support a multitude of wireless RF applications. Superb performance is achieved when used in either 50 Ω or 75 Ω terminating impedance applications.

The F2972 and F2976 use a single positive supply voltage of either +3.3 V or +5.0 and are compatible with either 1.8 V or 3.3 V control logic.
