1. A radio frequency system comprising:

  • a first transmission path configured to provide a first radio frequency signal; and

    a second transmission path including a power amplifier configured to provide a second radio frequency signal, a multi-throw switch configured to provide the second radio frequency signal to a selected output of a plurality of outputs of the multi-throw switch, and a matching network including a passive impedance element in series between an output of the power amplifier and an input of the multi-throw switch, and the multi-throw switch having an input impedance configured to damp a standing wave resonance in the second transmission path due to coupling with the first transmission path when the first transmission path is active.
