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
