Abstract
A hybrid power module for supplying a power to a power amplifier is provided. The hybrid power module includes a DC-DC converter and a linear regulator. The DC-DC converter provides a first current to the power amplifier via a first inductor according to an operating frequency and an envelope tracking signal. The linear regulator provides a second current to the power amplifier via a first capacitor according to the envelope tracking signal. A switch-mode power supply (SMPS) ripple voltage caused by the DC-DC converter is reduced by the linear regulator.
