Description
Technical field
The present invention relates to communication technical field, more particularly, to a kind of TE moulds dielectric resonance device.
Background technology
Wave filter is the main components in electronic equipment, and it can be filtered to various power supplys, signal etc., to ensure electricity
The stability and reliability of road operation.
Wave filter is the important radio frequency unit in GSM, in a communications system, in the defeated of active circuit
Enter output end it is at different levels between wave filter generally existing, each wave filter has each different function.Wave filter is wireless communication system
One indispensable device, the communication quality of its performance quality direct relation whole system.The function of wave filter includes：Keep away
Exempt to make receiver front end saturation because transmitting terminal output signal leaks；Remove as a kind of interference signal such as image frequency；Reduction comes from
The Power leakage of the local oscillator of antenna end；And interference between the simultaneous different communication systems of weakening etc..Therefore it
There must be the characteristics such as precipitous rising, trailing edge decay, good group delay.
With the development of radio communication, wave filter research constantly makes further progress.In all Modern wireless communication equipment
Radio-frequency front-end in, microencapsulated, performance be good, it is inexpensive, be easily installed the wave filter used, be always that related device is small-sized
Change, the emphasis of miniaturization.Modern cellular mobile communication, WLAN are the development of the wireless communication technology of representative, will be right
The frequency selection of part successive bands produces interference.On the one hand, it is necessary to be suppressed these interference to improve the performance of system.
On the other hand, it is also required to weaken above-mentioned air interference in some occasions to protect the normal work of other systems
Make, such as when Aircraft Vectoring System works, it is desirable to the above-mentioned signal for being used for wireless access purpose on aircraft is weakened.
Therefore, how the superior bandstop filter of design performance just seems very necessary.
It is increasingly crowded with communications band, more and more higher is required to performance of filter, conventional metals cavity filter is due to Q
The limited performances such as value, volume, it can not meet high target requirement of the communication system to wave filter.
Dielectric filter is the important means for solving this contradiction.Wherein, TE01 moulds dielectric resonator has Q values height, temperature
Spend coefficient and wait good characteristic well, more and more important effect is played in dielectric filter design.
TE01 mould dielectric resonator forms and medium fixing device are the cores of TE01 moulds dielectric filter design, and it is closed
Whether manage the electrical property for directly influencing dielectric filter, passive intermodulation and reliability.
Fig. 1 is traditional TE01 moulds dielectric resonator form.Wherein, TE01 moulds medium resonant rod 5 is TE01 mould dielectric resonances

The bottom surface of mould medium resonant rod 5 is provided with stopper slot, for spacing lower support base 62.With support base 62 at present by TE01 mould dielectric resonances
Heat transfer caused by bar 5 is to cavity bottom.TE01 moulds medium resonant rod 5 is bonded at one by Special high-temperature glue and lower support base 62
Rise, form an entirety.
Fig. 2 is fixed form of traditional TE01 moulds dielectric resonator in cavity.TE01 moulds dielectric resonator 2 in Fig. 1
Entirety is to be fixed on the bottom of cavity 1 by connector 7, and connector 7 is pan head screw.
Traditional TE01 moulds dielectric resonator and the excellent of fixed form, shortcoming in Fig. 1 and Fig. 2 is as follows：
Advantage：
It is simple in construction；
It is easy for installation.
Shortcoming：
TE01 mould dielectric resonators are locked in cavity bottom by pan head screw, and its top is hanging, can cause lower support base bottom
Portion's stress is larger, and especially when cavity side is filled, or reverse side is installed, its stress is bigger, and it is broken to greatly increase lower support base bottom
The risk split.
Pan head screw can influence the electrical property of TE mould dielectric resonators, especially can reduce chamber in high band, pan head screw
The Q values of body, meanwhile, pan head screw will cause the first harmonic of cavity, multiple harmonic to be drawn close to basic frequency, deteriorate proximal inhibition.
