High Linearity Broadband SP2T F2976 5MHz to 10GHz Datasheet Description Features (75) The F2976 is a single-pole double-throw (SP2T) reflective RF Low insertion loss: switch featuring high linearity and wide bandwidth. This device is 0.23dB at 204MHz optimized from 5MHz to 1.8GHz to support downstream cable 0.34dB at 1.8GHz modem future migration for DOCSIS 3.1 applications, and operates High Isolation: 40dB at 1.8GHz at up to 10GHz to support a multitude of wireless RF applications. P0.1dB compression of +37dBm at 204MHz Superb performance is achieved when used in either 50 or 75 Second Harmonic: -100dBc at 204MHz terminating impedance applications. Third Harmonic: -120dBc at 204MHz The F2976 uses a single positive supply voltage of either +3.3V or Composite Second Order Distortion > 100dBc +5.0V and is compatible with either 1.8V or 3.3V control logic. Composite Triple Beat Distortion > 100dBc Competitive Advantage Features (50) The F2976 provides extremely low insertion loss across the entire Low insertion loss: bandwidth while providing superb distortion performance. 0.40dB at 2.4GHz Optimized for DOCSIS 3.1 applications up to 1.8GHz 0.55dB at 8GHz Optimized for Wi-Fi applications up to 5.9GHz High Isolation: Low insertion loss 34dB at 2.4GHz High isolation High Linearity: Fast switching IIP2 +125dBm at 2.4GHz No external matching required IIP3 +77dBm at 2.4GHz P0.1dB compression of +40dBm at 2.4GHz Second Harmonic: -100dBc at 2.4GHz Typical Applications Third Harmonic: -110dBc at 2.4GHz Broadband Cable DOCSIS 3.0 / 3.1 Set top box CATV filter bank switching Block Diagram Wi-Fi Figure 1.

Pin is internally pulled up to 2.5V CTL 11 LS through a 500k resistor. Power supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close as 12 V CC possible to pin. Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple EP ground vias to provide heat transfer out of the device into the PCB ground planes. These multiple ground vias are also required to achieve the specified RF performance. 2017 Integrated Device Technology, Inc. 2 Rev O April 19, 2017
