Abstract

Abstract

A 40 kW, 204 MHz solid state RF amplifier is being developed for the 800 MeV electron storage ring at Hefei Light Source. The solid state amplifier is composed of 130 amplifier units combined by three-stage combiners in two towers. Some prototypes of key components have been manufactured and tested, which include a 2.5 kW 8-way combiner, a 20 kW 8-way combiner, a 40 kW 2-way combiner and 10 amplifier units. The output port’s VSWR of all combiners is not over 1.05. The amplifier unit's gain reaches 26 dB. Unbalance of gain and phase is less than 0.1 dB and 5°, respectively, satisfying the design requirements.
