Abstract
A device includes an amplifier having an input terminal and an output terminal. The input terminal is configured to receive a radio frequency (RF) input signal. The device includes an output network coupled to the output terminal of the power amplifier and a first passively tunable integrated circuit (PTIC) coupled to the output network. The first PTIC includes a direct-current (DC) bias voltage input terminal configured to receive a fixed bias voltage, a control signal input terminal configured to receive a time-varying control signal, wherein the fixed bias voltage in combination with the time-varying control signal sets an operating reference point of the first PTIC, and an input terminal electrically connected to the output terminal of the amplifier, wherein a change in an output voltage signal generated by the power amplifier causes the first PTIC to modify a first effective impedance of a load presented to the power amplifier via the output network.
