DEVELOPMENT OF 4-WAY 81 . 25 MHZ 20 kW HIGH POWER COMBINER USING PARALLEL PLATE STRUCTURE *

The recent development of semiconductor technology has proved that solid-state RF amplifier is a quite effective alternative high power RF source for numerous accelerator applications. To develop a high power SSPA system, high power combiner is required to combine the RF power from a lot of solid-state RF module [1]. The parallel plate RF power combiner, which is designed to combine various high power modules, is developed for RAON (Rare the rare isotope accelerator complex for online experiment). In this presentation, the status of developed 81.25 MHz 20 kW power combiner will be described.
