Abstract: The present invention relates to an adaptable RF impedance translation circuit that includes a first group of inductive elements cascaded in series between an input and an output without any series switching elements, a second group of inductive elements cascaded in series, and a group of switching elements that are capable of electrically coupling the first group of inductive elements to the second group of inductive elements. Further, the adaptable RF impedance translation circuit includes at least one variable shunt capacitance circuit electrically coupled between a common reference and at least one connection node in the adaptable RF impedance translation circuit, which includes control circuitry to select either an OFF state or an ON state associated with each of the switching elements and to select a capacitance associated with each variable shunt capacitance circuit to control impedance translation characteristics of the adaptable RF impedance translation circuit.

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.
