Abstract
The present invention relates to a radio frequency (RF) power measurement circuit that measures delivered power to a load. The RF power measurement circuit includes a measurement RF transmission line coupled to the load, and measurement and power calculation circuitry coupled to either end of the measurement RF transmission line to measure an RF input signal feeding the measurement RF transmission line and to measure an RF output signal fed from the measurement RF transmission line to the load. The measurement and power calculation circuitry uses the measured RF input and output signals to calculate and provide a delivered power signal that is indicative of the delivered power to the load.
