摘　　要：通过采用移动通信基站双工器频率温度系数(FTC)的测量方法和得到的实验数据,来设计介质加载谐振腔滤波器,包括介质材料的选择和微调机构的设计。实验表明,用该方法设计的介质滤波器的频率温度系数能满足下一代移动通信、ITFS、MMDS和其它带宽相对极窄应用场合的要求。The measuring method and test results of frequency temperature coefficient （FTC） of diplexers used in base station of mobile communication systems are cited and adopted in order to study FTC of dielectric loaded cavity filter. If the dielectric material＇s FTC is properly selected and the trimming outfit is well designed, FTC of dielectric loaded cavity filter is able to meet the requirements of the next generation mobile communication systems, such as IFTS, MMDS and the others which have the relative narrow passband and strict FTC.
