Abstract
Embodiments of the present disclosure relate to radio frequency (RF) transmitter circuitry, which includes non-inverting path power amplifier (PA) circuitry, inverting path PA circuitry, and RF transformer circuitry. The non-inverting path PA circuitry provides a non-inverting RF signal and a first power supply (PS) signal to the RF transformer circuitry, such that the first PS signal has a first ripple voltage. The inverting path PA circuitry provides an inverting RF signal and a second PS signal to the RF transformer circuitry, such that the second PS signal has a second ripple voltage. The RF transformer circuitry additively combines the non-inverting RF signal and the inverting RF signal to provide an RF output signal, such that effects of the first ripple voltage and the second ripple voltage are substantially cancelled from the RF output signal.
