Abstract: A tuning system for controlling a voltage controlled oscillator is described herein. The tuning system makes use of a dual edge phase detector.
Abstract: A modular RF power system allows multiple power supplies to combine their RF output power as a single system and deliver it to a common resonant circuit. For flexibility and commonality, each power supply is designed to be separately powered by AC line voltage (aka AC Mains). The AC voltage supplied to each power supply may differ due to differing AC distribution line length, line impedance, wire gauge, or different supply generation locations.
