1. An apparatus comprising:

  • a first matching circuit comprising multiple stages configured for selectively coupling in series;

    a second matching circuit comprising multiple stages configured for selectively coupling in series;

    an amplifier coupled to the first and second matching circuits, the first matching circuit provides input impedance matching for the amplifier, and the second matching circuit provides output impedance matching for the amplifier; and

    a selectable signal path from within the first matching circuit to within the second matching circuit that bypasses the amplifier.
