1. A system, comprising:
a Radio Frequency (RF) signal generator configured to generate a plurality of RF signals including a first RF signal and a second RF signal, the first RF signal being phase-shifted relative to the second RF signal in accordance with an input command;
a plurality of amplifier chains configured to process the plurality of RF signals to produce a plurality of amplified RF signals, each amplifier chain including a plurality of amplifiers connected in series, and an amplifier of the plurality of amplifiers configured to be provided with a tunable gate voltage prior to receipt of an RF signal of the plurality of RF signals;
a plurality of voltage sources configured to generate a plurality of offset voltages; and
power gating circuitry configured to apply a master voltage to the plurality of amplifiers, wherein the tunable gate voltage for each amplifier corresponds to an addition of an offset voltage of the plurality of offset voltages to the master voltage.
