Abstract
An RF power amplifier is presented herein including an RF source for providing a train of RF pulses having a fixed frequency and wherein each pulse is of a fixed amplitude and duration. A bridge circuit includes a first circuit having a first transistor switching means for, when on, connecting a DC voltage source across a load for DC current flow therethrough in a first direction. The bridge circuit includes a second circuit including a second transistor switch for, when on, connecting the DC voltage source across the load for DC current flow therethrough in a second direction. A switch driver control serves, when enabled, to pass the RF pulses for driving the first and second transistor switches on and off at a frequency dependent upon that of the RF signal and in such a manner that current from the DC voltage source alternately flows in the first and second directions through the load. Turn-on signals are provided and selectively applied to the switch driver control for enabling the switch driver control for passing the RF pulses to the transistor switches.
