Abstract:
1. A radio frequency (RF) power converter comprising: a switching circuit operable to receive a power source voltage, the switching circuit being switchable so as to generate a pulsed output voltage from the power source voltage; a switching controller operable to be activated and deactivated, wherein the switching controller is configured to switch the switching circuit so that the switching circuit generates the pulsed output voltage when the switching controller is activated; a low-drop out (LDO) regulation circuit operable to be activated and deactivated, the LDO regulation circuit being configured to generate a supply voltage when the LDO regulation circuit is activated; and an RF filter coupled to receive the pulsed output voltage from the switching circuit and the supply voltage from the LDO regulation circuit, the RF filter being operable to alternate between a first RF filter topology and a second RF filter topology, wherein the first RF filter topology is configured to convert the pulsed output voltage from the switching circuit into the supply voltage and the second RF filter topology is configured to filter the supply voltage from the LDO regulation circuit to reduce a ripple variation in a supply voltage level of the supply voltage.
