1. An apparatus comprising:

  • a first plurality of RF power amplifier circuits comprising;

    a first RF power amplifier circuit configured to receive and amplify a first RF amplifier input signal to provide a first RF amplifier output signal; and

    a second RF power amplifier circuit configured to receive and amplify a second RF amplifier input signal to provide a second RF amplifier output signal; and

    a first weakly coupled RF network comprising;

    a first pair of weakly coupled RF resonators coupled to the first RF power amplifier circuit, wherein the first weakly coupled RF network is configured to process an RF signal associated with the first RF power amplifier circuit using the first pair of weakly coupled RF resonators; and

    a second pair of weakly coupled RF resonators coupled to the second RF power amplifier circuit, wherein the first weakly coupled RF network is further configured to process an RF signal associated with the second RF power amplifier circuit using the second pair of weakly coupled RF resonators.
