Abstract: A matching circuit comprising: an input-terminal configured to be connected to an active-circuit; an output-terminal configured to be connected to a downstream component; a current-source configured to provide a disabled-current; one or more diode-modules, each comprising a diode and a biasing-resistor in parallel with each other; and a reactive-matching-component that has a reactive impedance. The current source is configured to pass the disabled-current through the one or more diode-modules and the reactive-matching-component when the matching circuit is in a disabled-mode of operation such that they contribute to the impedance of the matching circuit between the input-terminal and the output-terminal.

Abstract: A Doherty amplifier comprising: a main-power-amplifier having a main-amp-output-terminal; a peaking-power-amplifier having a peaking-amp-output-terminal; a combining node; a main-output-impedance-inverter connected between the main-amp-output-terminal and the combining node; and a transformer connected between the peaking-amp-output-terminal and the combining node.
