摘　　要：为了提高卫星通信中滤波器的低气压功率阈值,采用了TM模介质滤波器技术。分析了同轴滤波器和TM模介质滤波器的场强、电压和储能,可看出,TM模介质滤波器的电磁场主要分布在介质谐振器内部,电压和场强远小于同轴滤波器。通过试验验证对比,TM模介质滤波器技术大幅度的提高了滤波器的低气压功率阈值,同时降低了滤波器的体积和质量。To increase the threshold of low-pressure discharge in satellite communication, TM-mode dielectric will be a-dopted. The electromagnetic field, voltage and stored energy of coaxial and TM-mode dielectric have be analyzed, from that, the electromagnetic field of TM-mode dielectric resonator is restricted in the resonator; the electric field, voltage of TM-mode filter are smaller than the coaxial filter.The test result is presented; power threshold with TM-mode filter is improved, simul-taneously ,the volume and weight is decreased.
