A tm01 dielectric resonator assembly device

Abstract

The invention relates to a TM01 medium resonator assembling device. A transitional metal band is introduced, so that the reliability of assembly of a TM01 medium resonator and a metal cavity is guaranteed. The TM01 medium resonator assembling device is characterized in that the TM01 medium resonator is welded on the transitional metal band in a single-end manner; the transitional metal band on which the TM01 medium resonator welded in a single-end manner is arranged on a cavity cover board by a thread on the transitional metal band; and therefore, a TM01 medium filter can be stably and reliably assembled. The TM01 medium resonator assembling device is suitable for any TM01 medium resonator and is particularly suitable for products which have relatively high requirement on the first pass yield of the TM01 medium filter, are relatively complicated in design and need massive overhaul and maintenance in the later stage.

Description

technical field

[0001] The invention relates to the technical field of dielectric resonators, in particular to a TM01 dielectric resonator assembly device. Background technique

[0002] With the rapid development of wireless communication, the third-generation mobile communication systems of WCDMA, CDMA2000 and TD-SCDMA are being constructed on a large scale, and the fourth-generation mobile communication has entered the commercial trial stage. There are very strict controls on the weight and weight. As a key component of the radio frequency front-end of the mobile communication base station, the transceiver filter, its performance will also directly affect the communication quality. For this reason, it is necessary to reduce the size and weight of the filter without reducing the performance of the filter.

[0003] Microwave filters that meet the above-mentioned uses have two remarkable features: small insertion loss and good selection performance. To this end, these filte...
