1. A radio frequency (RF) receiver comprising:

  • a plurality of receive bands each having an input selectably coupled to an antenna; and

    circuitry being coupled between said input and ground for each of the plurality of receive bands, and having a control terminal that is selectably coupled to a supply voltage or to ground for each of the plurality of receive bands,wherein the circuitry is configured to;

    activate an input of one of the plurality of receive bands by selectively grounding a control terminal related to the activated receive band; and

    deactivate the remaining receive bands by selectively coupling the remaining control terminals to the supply voltage so as to couple the input of the remaining receive bands to ground, thereby providing band isolation and electrostatic discharge (ESD) protection to the plurality of receive bands.
