通过使用 MEM 微继电器调谐的 VHF 射频带通滤波器在 25 W 射频功率输入水平下运行。在调谐工作频率下，滤波器插入损耗小于 1 dB，滤波器工作 Q 约为 10。MEM 微继电器在 25 W RF 功率下进行了 5300 万次工作循环的寿命测试，没有发现触点出现明显退化。讨论了微继电器的开发以及 CAE 工具在滤波器开发中的使用。 © 2001 John Wiley & Sons, Inc. Int J RF and Microwave CAE 11: 261–275, 2001。
A VHF RF bandpass filter tuned through the use of MEM microrelays was operated at a 25 W RF power input level. The filter insertion loss was less than 1 dB at the tuned frequencies of operation, and the filter operating Q was about 10. The MEM microrelays were life tested for 53 million operating cycles at 25 W RF power, and no significant degradation to the contacts was noted. The development of the microrelay and the use of a CAE tool in the filter development are discussed. © 2001 John Wiley & Sons, Inc. Int J RF and Microwave CAE 11: 261–275, 2001.
