1. A method of processing a multiband signal, the method comprising:

  • receiving a multiband signal at an antenna of a wireless device;

    filtering the multiband signal using a plurality of bandpass filters to obtain a first signal and a second signal;

    determining the first bandwidth of the first signal and the second bandwidth of the second signal;

    amplifying the first signal to obtain a first amplified signal;

    configuring a first resonant circuit to filter first noise associated with the second bandwidth from the first amplified signal;

    filtering the first noise from the first amplified signal using the first resonant circuit to obtain a first filtered amplified signal;

    amplifying the second signal to obtain a second amplified signal;

    configuring a second resonant circuit to filter second noise associated with the first bandwidth from the second amplified signal;

    filtering the second noise from the second amplified signal using the resonant circuit to obtain a second filtered amplified signal; and

    combining the first filtered amplified signal and the second filtered amplified signal.
