摘　　要：介绍了人造卫星用７０．５ｋＨｚ和９４．５ｋＨｚ差接桥型压电陶瓷滤波器的设计原理和试验结果。该滤波器的主要特点是通带宽且平坦、波动小。This paper described the design principle and the experimental results of 70.5 kHz and 94.5kHz differential bridge piezoelectric ceramic filters used in satellite.These filters show excellent performances such as large passband width,flat passband,small ripples and low insertion loss.

关 键 词：陶瓷滤波器 差接桥型 通带宽度 人造卫星
