中文摘要：

研制了一台高频高功率全固态放大器（SSA）,用于合肥光源800MeV电子储存环高频系统的带束流运行。固态放大器的功率合成系统可按8×6或8×8方式进行组合,各有48个和64个功放模块参与功率合成。测量了功率分配器和合成器各端口的S参数及功放模块的增益特性,功放模块输出650 W时的增益为24dB,分配器和合成器公共端的驻波比均优于1.07。进行了高功率测试,两种组合的输出功率分别达到33kW和45kW,合成效率约为95%。固态放大器目前运行于48路合成方式,输出功率为20kW时,储存环束流流强达到460mA,束流功率为7.5kW。

英文摘要：

A solid state amplifier（SSA）was developed and used on the beam operation for 800 MeV electron storage ring in Hefei Light Source（HLS）.Two combining ways（8×6and 8×8）were designed for SSA,in which 48 and 64amplifier units were employed,respectively.The S parameters of combiners and splitters and the gain of amplifier units were measured by a network analyzer.The gain of amplifier unit is 24 dB at 650 W,and the SWR of combiners and splitters is less than 1.07.The SSA output powers of two combining ways are up to 33 kW and 45 kW respectively,and the combining efficiency is about 95%.The SSA is assembled in the 48-way combination and operates in the RF system of storage ring.When the SSA output power is 20 kW,the beam of 460 mA is accumulated in the storage ring,whose power is 7.5kW.
