A modulation format switch in signal communication with an amplifier, which produces a plurality of modulation format signals, and a load is described. The modulation format switch includes at least one matching network in signal communication with the amplifier and the load, where the at least one matching network capable of having a plurality of impedance values corresponding to the plurality of modulation format signals. The modulation format switch also includes a controllable element in the matching network, the controllable element capable of having more than one impedance value.
