Design of cavity power combiner with rotatable online decoupling system
摘要
Abstract
To facilitate online replacement and maintenance of solid-state power sources in particle accelerators,a cavity power combiner with online decoupling capability is required.While cavity combiners offer high power capacity,adjustable input coupling has not been achieved online.Therefore,we designed a 650 MHz eight-in-one cavity power combiner with a rotatable decoupling system.By integrating non-contact open-circuit slits at the RF input port and separating the coupling loop from the cavity,we enabled online rotation adjustment of the magnetic coupling loop.This adjustment allows real-time tuning of input coupling according to the operational status of solid-state power sources,facilitating hot-swapping and efficiency optimization.Simulation results demonstrate high synthesis efficiency and minimal power loss,with excellent amplitude consistency between input and output ports(deviations within 0.25 dB).The ability to adjust coupling online enhances RF isolation at input ports,enabling seamless hot-swappable replacement of power amplifier modules and significantly improving maintainability and flexibility.关键词
