【摘要】 S波段1kW固态放大器用于北京正负电子对撞机直线加速器大功率速调管的微波激励,阐述了其工作原理和性能指标,并对其核心部分——580W放大器模块作了重点介绍,该放大器达到的主要技术指标如下:工作频率为2856MHz,输出最高脉冲功率为1030W(在放大器合成后输出端测量),脉冲宽度为2—10μs,脉冲前沿/脉冲后沿分别是88ns/40ns,脉内平顶为0.7％,该放大器自2001年5月在加速器上运行到现在,运行状态良好。更多还原

【Abstract】 This paper presents the development of a 1kW S-Band RF Solid State Amplifier (SSA) for the BEPC Linac. IkW peak power with a pulse width of 2-10μs under low voltage operation is achieved by combining eight 160W high power Solid State Amplifiers using a low-loss(0.3dB) combiner. Other key performance parameters are: RF phase drift during pulse ≤±1 degree, RF rise time/fall time is 88ns/40ns, RF pulse flatness is 0.7 % , and RF power stability is 0.1dB.更多还原
