Description
Technical field
The present invention relates to a kind of novel medium waveguide filters, belong to telecommunication transmission equipment technical field.
Background technique
Waveguide filter includes that one or filter have the function of frequency-selecting, can pass through required frequency with crossover frequency
Signal and restrain unwanted frequency signal, be one of the core design in radio technology.
Traditional waveguide filter is coaxial filter, basic structure are as follows:, on one piece of ceramics, on 2 opposite faces
Several through-holes are laterally dug, each through-hole region forms a resonant element, with gold on one of face in through-hole direction
Belong to and print a circuit formation coupling, other regions and hole inner wall all metal coverings, such structure are formed Contiuum type TEM
Mould coaxial filter.
The filter of such structure type its electrical comprehensive performance not very in West Europe it is high, bearing power, Q value, in band
Loss etc. is by the space further increased.
Summary of the invention
For the present invention in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structurally reasonable, the one kind for having fine transmission performance is new
Type dielectric waveguide filter.
Thus the technical solution adopted by the present invention is that: a kind of novel medium waveguide filter has two kinds or less connection shapes
One of formula or two kinds of combination:
1) include several resonant elements for being arranged successively setting, offer window-shaped at the plate engaged between adjacent resonant element
At coupling；
2) include several resonant elements for being arranged successively setting, notch is offered between adjacent resonant element and forms coupling；
3) there is the combination for 1), 2) planting structure type, that is, there is multilayer resonant element, pass through fluting shape between same layer resonant element
At coupling, window is offered at the plate that engages between upper and lower level resonant element and forms coupling.
1) described the plants in structure type, the window opened up at the plate engaged between adjacent resonant element is coupled in same
On straight line and the axis of resonant element is overlapped setting.
2) described the plants in structure type, the fluting form having has following two structure type:
1) notch opened up between adjacent resonant element extends transversely through entire resonant element, opens up direction and resonance unit axis side
To on the contrary, the notch longitudinal direction opened up is blind slot structure type；
2) notch opened up between adjacent resonant element is formed at middle part and is connected, and the form that two sides form through slot forms coupling.
Described 1) to plant structure type, the form of each notch is consistent.
Described 2) to plant in structure type, two notches are symmetrical arranged, and form the structure type of double surface grooving.
The invention has the advantages that 1) the Q value of the resonant element of TEM mould is usually between 250 ~ 1000, Medium Wave Guide resonance
Unit can be accomplished between 800 ~ 2000.
2) the receiving power of TEM mould is generally between 1W ~ 30W, and Medium Wave Guide bears power between 10W ~ 60W.
3) for the Out-of-band rejection of TEM mould generally in 70dB, the Out-of-band rejection of Medium Wave Guide can accomplish 90dB or more.
4) TEM mould band internal loss be difficult to accomplish within 0.5dB, Medium Wave Guide band internal loss can accomplish 0.3dB with
It is interior.
5) TEM mould is difficult to realize automation debugging due to oneself reasons in structure, and Medium Wave Guide consistency is relatively preferable,
It is expected that future may be implemented to be fully automated production.
