1. A receiver for a wireless communication system that is operable in at least a first mode of communication and a second mode of communication, the receiver comprising:

  • an antenna for receiving a communication signal;

    a first BAW resonator for receiving an RF signal provided at an output of the antenna;

    a low noise amplifier having an adjustable input or output impedance for interacting with operating characteristics of the first BAW resonator; and

    a mixer circuit coupled to the low noise amplifier, the mixer circuit mixing an RF signal with a signal from a local oscillator so as to generate an intermediary frequency, wherein the input impedance of the low noise amplifier is adjusted so as to operate the receiver in the first or second mode of communication.
