Description

A kind of novel miniaturization pectination ceramic tube medium cavity body filter
Technical field
The present invention relates to microwave device technical field more particularly to a kind of novel miniaturization pectination ceramic tube medium cavitys Filter.
Background technique
Microwave filter is the essential Primary Component in the systems such as electronic countermeasure, radar, communication, and pectination cavity Filter belongs to one kind of microwave filter, have it is compact-sized, be electromagnetically shielded, Insertion Loss is low, rectangular degree is high, Out-of-band rejection is good The advantages that.The typical structure of pectination cavity body filter is as shown in Figure 1, mainly by wire chamber 1, metal tuning screws 2, gold at present Belong to tuning nut 3, microwave connector 4 etc. to constitute, wire chamber realizes the coupling of the resonator element and unit of filter, metal The accurate tuning of tuning screw realization filter.
Current this conventional pectination cavity body filter has the disadvantages that.
First is that cavity body filter resonant element is related to wavelength, using air dielectric in order to obtain good microwave property Load, causes cavity body filter bulky, if certain centre frequency is the conventional pectination cavity body filter of 4.5GHz, long × wide × Height is unfavorable for the miniaturization of modern electronic equipment and system having a size of 50mm × 25mm × 15mm.
Second is that being tuned using metallic screw, metal nuts locking, volume non-resultant product microwave property shared by metal nuts, no Conducive to cavity body filter miniaturization.
Summary of the invention
The object of the invention is that a kind of novel miniaturization pectination ceramic tube medium cavity body filter is provided, on solving State problem.
To achieve the goals above, the technical solution adopted by the present invention is that such: a kind of novel miniaturization pectination ceramic tube Jie Matter cavity body filter, including Can cavity, metal tuning needle/column, ceramic dielectric load pipe and connector, wherein described The opposite two sidewalls of Can cavity are provided with cavity through-hole, and the ceramic dielectric load pipe protrudes into the Can chamber The cavity through-hole of body wherein side, the metal tuning needle/column protrude into the cavity through-hole of the Can cavity other side.
The present invention is cooperateed with by four Can cavity, metal tuning needle/column, ceramic dielectric load pipe and connector parts Work improves packing material Q value using ceramic tube coated by dielectric and tuning, realizes low-loss design;Added using ceramic tube medium It carries and realizes 1/4 wave resonance unit physical size of compression filter, realize Miniaturization Design;Cavity is entered using debugging ceramic tube Length in hole realizes cavity body filter debugging design, generates microwave resonance, realizes microwave signal filtering.Miniaturization of the invention Pectination ceramic tube medium cavity body filter working frequency range is covered as 100MHz~20GHz, in the alternative traditional pectination chamber of the frequency range Fluid filter.
As a preferred technical scheme: the ceramic dielectric load pipe is Nian Jie with the cavity through-hole.
The fastening assembly of small cavity filter ceramic tube is preferably realized using adhering process.
As a preferred technical scheme: the metal tuning needle/column and the cavity through-hole weld.
Preferably realize that small cavity filter tunes needle/column trim designs using soldering process.
Compared with the prior art, the advantages of the present invention are as follows: the present invention is small-sized by pectination ceramic tube medium cavity body filter Change (the pectination cavity body filter that such as certain centre frequency is 4.5GHz, length × width × height is having a size of 25mm × 9.5mm × 4mm), nothing Fastening accessory, filter medium load tuning, easily designed, processing and manufacture are suitable for mechanical oscillation, wide temperature work etc. The development and production of filter in harsh environment have important applying value in modern electronic communication system.
