Abstract:
1. An apparatus, comprising: a memory to store computer instructions; and a controller coupled with the memory, wherein the controller, responsive to executing the computer instructions, performs operations comprising: obtaining a voltage at an output of an RF matching network, wherein the RF matching network comprises one or more variable reactive elements; and adapting the matching network according to the obtained voltage to increase an RF voltage at the output by varying the one or more variable reactive elements, wherein the variable reactive elements comprise at least one of a semiconductor varactor, a micro-electro-mechanical systems (MEMS) varactor, a MEMS switched reactive element, a semiconductor switched reactive element, or a ferroelectric capacitor, wherein the voltage is obtained using a voltage detector coupled to the output via a variable voltage divider.
