固态微波放大器的开发

Development of a Solid-state Microwave Amplifier

2.5kW/352MHz无条件稳定的微波固态放大器在意大利Legnaro国家实验室研制成功并通过测试。该放大器由9个350W推挽工作方式的功率模块构成,每个模块采用1个环形器和1个终端电阻作为保护装置。该放大器为独立相位超导直线加速器的中β超导腔提供微波功率而开发,具有高效率、线性度好、可靠性高以及低成本的特点。文章介绍了该放大器的技术特点和测试效果。

A 2.5 kW, 352 MHz unconditionally stable RF amplifier for CW and pulsed operation has been built and tested at Legnaro National Laboratory, Italy. The amplifier is composed of 9 modules, each containing one push-pull 350 W MOSFET equipped with a circulator and a RF termination. High efficiency, linearity, reliability and low cost are the main features for this device, which is developed for intermediate β independently phased superconducting cavity linacs. Technical characteristics of the amplifier and test results are presented.
