Abstract

The invention relates to a preparation technology of a ceramic dielectric resonator for TM communication applied to microwave components such as dielectric resonators, filters and oscillators in satellite communication and mobile communication systems and a GPS global positioning system. Microwave dielectric ceramic is prepared from the following raw materials: barium oxide (BaO), titanium dioxide (TiO2), zinc oxide (ZnO) and niobium pentoxide (Nb2O5) and a trace amount of doped additives copper oxide (CuO) and manganese oxide (MnO); and the components are subjected to solid-phase reaction procedures of burdening, mixing, ball-milling, pelleting, molding, bowl filling, rubber discharging and sintering to fire the microwave dielectric ceramic. The technology has the advantages of being low in sintering temperature, energy-saving, environment-friendly, high in dielectric constant, high in quality factor and stable in resonance frequency temperature characteristics.

Description

technical field [0001] The invention relates to a preparation process of a ceramic dielectric resonator for TM mode communication. The resonator is used in microwave components such as dielectric resonators, filters, oscillators and GPS global positioning systems in L-band satellite communication and mobile communication systems. Background technique [0002] At present, with the rapid development of my country's aerospace technology and satellite communications, multi-band fixed broadcast communication satellites, dedicated broadcast satellites, live broadcast satellites, mobile broadcast satellites, mobile communication satellites and dedicated GPS global positioning and safety navigation satellites will be formed. As well as the further increase in the demand for transmission bandwidth of data services dominated by IP services, the development and application of the longer wavelength L-band has increasingly become the focus of attention. At the same time, it also drives t...
