| Abstract: | 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. |
