Abstract
The invention relates to the field of radio frequency devices, and discloses a method for stable installation of a dielectric resonator in a metal cavity. According to the method, the dielectric resonator is welded in the metal cavity to achieve stable connection of the dielectric resonator and the metal cavity, the tensile property of the dielectric resonator is improved greatly, it is ensured that the dielectric resonator does not disengage easily after staying in a high-temperature high-moisture environment for a long time, and a finally produced dielectric cavity filter has the advantages of being high in reliability, wide in application range, long in service life and the like. Furthermore, the method is suitable for bulk production and can be applied to dielectric cavity filters of any feed types and other radio frequency devices requiring dielectric resonators to be installed in metal cavities, and can be practically used and popularized conveniently.
Description
technical field [0001] The invention relates to the field of radio frequency devices, in particular to a method for stably installing a dielectric resonator in a metal cavity. Background technique [0002] In modern mobile communication technology, microwave radio frequency devices are an important part of communication equipment. Among them, dielectric cavity filters are widely used and Among all kinds of communication equipment, the key component is the dielectric resonator installed in the internal metal cavity. [0003] At present, the connection form of the dielectric resonator and the metal cavity is mainly glued. Although this method has the advantages of simplicity, easy operation and low cost, it has the disadvantages of poor stability and inability to withstand high temperature and high humidity for a long time. The reliability and application scenarios of dielectric cavity filters are greatly restricted. Contents of the invention [0004] Aiming at the problem...
