Description
Technical Field
The utility model relates to a wave filter field, in particular to wave filter that contains packing medium.
Background
In the design of a conventional filter, a duplexer and a multiplexer, the required frequency range cannot be reached due to the reasons that the overall dimension required by the product is smaller, the depth is shallower and the like, because the overall dimension is larger, the deeper the depth is, the lower the frequency is, and otherwise, the frequency is relatively higher, so that the design index cannot meet the requirement. In the prior art, a flange disc type resonance column is used for reducing the frequency, but the scheme has the defects that the insertion loss index does not meet the requirement and the cost of the flange disc type resonance column is high.
SUMMERY OF THE UTILITY MODEL
To the deficiencies of the prior art, the main object of the present invention is to provide a filter containing a filler medium, which can reduce the frequency of the filter and reduce the cost.
In order to achieve the above purpose, the utility model provides a following technical scheme: a filter containing a filling medium comprises a cavity and a cover plate, wherein an input connector and an output connector are arranged outside the cavity, an input copper sheet and an output copper sheet are arranged in the cavity, a tuning screw is further arranged in the cavity, the filling medium is further arranged in the cavity, and the filling medium is an insulator with a dielectric constant larger than that of air.
Preferably, the filling medium fills the space between the cavity and the cover plate.
Preferably, the filling medium is plastic or ceramic or glass.
The utility model discloses have following advantage for prior art, its theory of operation is through increasing the packing medium, changes the air dielectric constant and reduces the frequency originally, avoids the resonance post to have the ring flange pattern. The design utilizes the insulator made of non-metal materials, changes the dielectric constant of the original air cavity according to the principle that the dielectric constant of the insulator is different from that of air, and therefore the required frequency and high-Q-value resonance single cavity is obtained. The insulating material with different dielectric constants can be adjusted freely according to requirements, so that the requirements are met. The scheme solves the problem of frequency band range of frequency meeting the requirement in the design of filters, duplexers and combiners due to the fact that the appearance size and the height are small. The problems that the insertion loss index cannot meet the requirement and the cost of the flange plate resonance column is high due to the use of the flange plate resonance column are solved. The dielectric constant of air is 1.000585, which is already small, and the dielectric constant of the insulator is larger than that of air, such as plastic, ceramic or glass, which is not only several times larger than that of air, thereby reducing the frequency, but also easy to process and convenient to be integrally placed in the cavity.

Preferably, the filling medium 8 is plastic or ceramic or glass.
The filter that contains packing medium 8 of this scheme, its theory of operation is through increasing packing medium 8, changes the air dielectric constant and reduces the frequency originally, avoids the resonance post to have the ring flange pattern. The design utilizes the insulator made of non-metal materials, changes the dielectric constant of the original air cavity according to the principle that the dielectric constant of the insulator is different from that of air, and therefore the required frequency and high-Q-value resonance single cavity is obtained. The insulating material with different dielectric constants can be adjusted freely according to requirements, so that the requirements are met. The scheme solves the problem of frequency band range of frequency meeting the requirement in the design of filters, duplexers and combiners due to the fact that the appearance size and the height are small. The problems that the insertion loss index cannot meet the requirement and the cost of the flange plate resonance column is high due to the use of the flange plate resonance column are solved. The dielectric constant of air is 1.000585, which is already relatively small, and the dielectric constant of the insulator is larger than that of air, such as plastic, ceramic or glass, which is not only several times larger than that of air, thereby reducing the frequency, but also easy to process and convenient to be integrally placed in the cavity 2.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
