The invention provides a dielectric filter and communication equipment, and relates to the technical field of wireless communication, the dielectric filter comprises a dielectric body and a pluralityof resonance units arranged on the dielectric body; each resonance unit comprises a resonance through hole and a frequency blind hole, and the resonance through hole is communicated with the frequencyblind hole; the radial size of the resonance through hole is different from that of the frequency blind hole, and a frequency debugging area is arranged on the resonance unit and used for tuning thefrequency of the dielectric filter. The dielectric filter and the communication equipment provided by the invention are small in size, light in weight and convenient to process, and further meet the communication requirement of miniaturization development on the basis of realizing the performance.
Description
Technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a dielectric filter and communication equipment. Background technique [0002] With the rapid development of communication technology, wireless communication equipment is becoming more and more compact, and the requirements of wireless communication equipment for high-sensitivity transmission / reception of signals are also getting higher and higher, making dielectric filters also in wireless communication. It is becoming more and more important. Compared with conventional cavity resonators, dielectric filters have the advantages of low loss, low cost, high temperature stability, and good harmonic suppression. [0003] However, most of the filters used in low-frequency communication currently have a large size, which is difficult to meet the communication requirements of the development of miniaturization of wireless communication equipment. Summary of the inventi...
