Abstract:
1. A circuit, comprising: a control system; a first amplifier section coupled to the control system, the first amplifier section being configured to amplify at least a portion of an input signal and produce a first amplified signal on a first signal path in a first mode of operation; a second amplifier section coupled to the control system, the second amplifier section being configured to amplify at least a portion of the input signal and produce a second amplified signal on a second signal path in a second mode of operation; an RF switch coupled to the control system and operable to route the input signal to the first amplifier section in the first mode of operation and to route the input signal to the second amplifier section in the second mode of operation; and an impedance inverter having an input coupled to the first and second signal paths.
