1. A power amplifying system configured to operate for a plurality of frequency bands, comprising:

  • an input matching network configured to perform input impedance matching for input signals in the plurality of frequency bands;

    a first frequency selecting module that is coupled to the input matching network and directs the input signal in each of the plurality of frequency bands to an input signal path associated with the frequency band;

    one or more transistors that receive the input signals in the plurality of frequency bands and amplify the input signals to generate output signals in the plurality of frequency bands;

    a bias circuit to bias the one or more transistors;

    an output matching network configured to perform output impedance matching for the output signals in the plurality of frequency bands; and

    a second frequency selecting module that is coupled to the output matching network and directs the output signal in each of the plurality of frequency bands to an output signal path associated with the frequency band.
