Problems solved by technology

As a result, the parasitic passband of the filter or duplexer made of it is too close to the main frequency passband, causing filter waveform distortion, increasing energy loss, resulting in a decrease in power factor, affecting the normal operation and use of communication equipment, and restricting fast develop

Abstract

The invention relates to a TM (Transverse Magnetic) mode dielectric resonator for controlling second harmonic migration. The dielectric resonator is a solid step column with a T-shaped longitudinal section; one end of the solid step column is coated with a metal layer or both ends are coated with metal layers; the upper part of the solid step column is provided with a first solid column, and the lower part of the solid step column is provided with a second solid column; the diameter of the first solid column is larger than that of the second solid column; the junction position between the first solid column and the second solid column is provided with a chamfering circular arc area; and the height of the second solid column is larger than 4.5mm. The invention provides the TM mode dielectric resonator which can control second harmonic migration. The dielectric resonator can inhibit a second harmonic wave at the position which is far away from a main frequency band.

Description

technical field [0001] The invention relates to a microwave dielectric resonator and belongs to the field of reciprocal microwave devices. Background technique [0002] With the announcement of my country's 3G standard, the deployment of wireless communication infrastructure has been fully rolled out. Among them, base station deployment is one of the important topics. In the current mobile communication, the radio frequency part of the mobile communication base station uses filters and duplexer resonators Most of them use silver-plated metal coaxial cavity, because the Q value of this coaxial cavity is limited (Q u About 3500), and the temperature stability of the resonant frequency is very poor (determined by the inherently large thermal expansion coefficient of the metal cavity), in order to prevent the frequency from drifting greatly with the change of the ambient temperature, the entire base station must work in a constant temperature environment , resulting in bulky bas...
