摘　　要：The application of HTSC (high temperature superconductor) microwave devices in a UHF digital trunking communication system is introduced.The replacement between the HTSC microwave devices and the normal microwave devices is conducted.The digital sensitivity of the base station in complex electromagnetic environment has been increased to 6 dB,as the results of the experiment indicated,and this means that the coverage radius of the base station has been improved about twice,that is to say,the coverage area can be extended to four times as large as that of the current method.The application of HTSC （high temperature superconductor） microwave devices in a UHF digital trunldng communication system is introduced.
