Abstract
The paper is a complete documentation of a microwave power controller for use with a Varian Associates Model PPS-2.5 AS high power industrial generator developed to improve the operating characteristics of our 2450 MHz irradiation facility. The paper includes theory of operation, photographs, circuit schematic drawings, wiring diagrams and a parts list of the controller. The controller makes the RF power output insensitive to low frequency line voltage fluctuations and also permits the RF power output to be programmed automatically. (Author)
