Description
Technical field
The utility model relates to a kind of structure of TEM mould coaxial dielectric ceramic resonator.
Background technology
TEM mould (transverse) coaxial dielectric ceramic resonator can be applicable to occasions such as low phase noise VCO, DRO/VCO oscillator, narrow band filter, duplexer, GPS, UHF electricity accent amplifier, radio communication, tuned oscillator.The knot of traditional TEM mould coaxial dielectric resonator comprises the leading foot 2 of ceramic dielectric block 1 and metal as shown in Figure 1.The cavity 3 that the center of ceramic dielectric block has two ends to connect, the inwall of this cavity has the layer of metal electrode layer, and leading foot is connected with the metal electrode layer of the inwall of an end of cavity.This TEM mould coaxial dielectric resonator forms final dielectric by sintering more normally by dry-pressing or hot injection forming.Because factors such as the pressure during moulding change, and the shrinkage during sintering is inconsistent, can influence the consistency of final products batch.For the bigger product of length dimension, also exist the centre position to shrink greater than two ends, the problem of irregular deformation appears.And, when making the dielectric resonator product of different size, needing the different mould of processing, the production cycle is longer, and cost is higher.
Summary of the invention
The utility model is intended to propose the structure of the TEM mould coaxial dielectric ceramic resonator of a kind of dimensional accuracy height, good product consistency.
This TEM mould coaxial dielectric ceramic resonator comprises leading foot two parts of ceramic dielectric block and metal.The cavity that the center of ceramic dielectric block has two ends to connect, the inwall of this cavity has the layer of metal electrode layer.Leading foot is connected with the metal electrode layer of the inwall of an end of cavity.Have on the ceramic dielectric block on the end face of metal leading foot and do not have metal electrode layer, all there is metal electrode layer four sides of ceramic dielectric block.The ceramic dielectric block of this TEM mould coaxial dielectric ceramic resonator is the dielectric of U-shaped groove to be arranged and the one flat plate dielectric is bonding with glass paste, high temperature sintering forms by one.
This TEM mould coaxial dielectric ceramic resonator is because its ceramic dielectric block is the dielectric of U-shaped groove to be arranged and the one flat plate dielectric is bonding with glass paste, high temperature sintering forms by one, can adopt large stretch of bonding method that cuts into discrete component again to make ceramic dielectric block, thereby can obtain dimensional accuracy height, product that parameter consistency is good.

Embodiment
As shown in Figure 2, the TEM mould coaxial dielectric ceramic resonator that the utility model proposes comprises leading foot 2 two parts of ceramic dielectric block 1 and metal.The cavity 3 (coupling aperture) that the center of ceramic dielectric block has two ends to connect, the inwall of this cavity has the layer of metal electrode layer.Leading foot 2 is connected with the metal electrode layer of the inwall of an end of cavity.Have the end face of metal leading foot 2 not have metal electrode layer on the ceramic dielectric block 1, all there is metal electrode layer four sides of ceramic dielectric block.Another end face can have metal electrode layer, also can not have metal electrode layer.What another end face had metal electrode layer is λ/4 mode of operations, and what another end face did not have metal electrode layer is λ/2 mode of operations.As shown in Figure 3, ceramic dielectric block 1 is the dielectric 11 of U-shaped groove to be arranged and one flat plate dielectric 12 usefulness glass pastes are bonding, high temperature sintering forms by one.
The ceramic dielectric block of this TEM mould coaxial dielectric ceramic resonator can adopt large stretch of method bonding, that cut into discrete component again to make.Manufacturing process is as shown in Figure 5: the mode by mechanical slotting on the medium sheet 32 of firing in advance, processing forms many grooves 33.The width of groove 33 and degree of depth equidimension are determined by design.Medium large stretch of 32 and another dull and stereotyped medium large stretch of 31 are bonding by glass paste, form firmly integral body 34 behind the high temperature sintering.And then by single ceramic dielectric block 1 of cutting formation.Make metal electrode layer by soaking into silver slurry or electroplating technology at the surfaces externally and internally of ceramic dielectric block 1 then, an end face forms open circuit surface therein, on the metal electrode layer of the inwall of an end of cavity, connect metal leading foot 2, promptly be made into the media ceramic resonator element.
Because the sintering temperature (about 900 ℃) of glass paste is lower than the sintering temperature (about 1400 ℃) of media ceramic, the sintering temperature (about 700 ℃) of the silver slurry of metal electrode layer is lower than the sintering temperature of glass paste, so the overall dimension of the TEM mould coaxial dielectric ceramic resonator that is made into this method and the size and the position of coupling aperture are determined precision height, high conformity by machining.This processing method also is fit to produce in batches.
As shown in Figure 4, the ceramic dielectric block 1 of this TEM mould coaxial dielectric ceramic resonator also can be by two have the dielectric 13 of U-shaped groove to be involutory,, high temperature sintering bonding with glass paste form.In this structure, the degree of depth of the U-shaped groove on every ceramic dielectric body 13 is half of U-shaped depth of groove on the ceramic dielectric body 11 shown in Figure 3.The ceramic dielectric block of this structure also can cut into the method for discrete component bonding with sheet, again and make, and all has the U-shaped groove on two ceramic sheets bonded to each other.
