Abstract
The invention discloses a high-power high-insulativity dielectric duplexer, wherein a transmission terminal, a reception terminal and an antenna terminal are removed from the interior to the exterior of a resonant cavity so that insulating dielectric body polytetrafluoroethylene for connecting the resonant cavity with each terminal in the existing duplexer is saved; and meanwhile, the transmission terminal, the reception terminal, the antenna terminal and a metal shielding case are made from an iron-nickel alloy material. Compared with the existing copper, the iron-nickel alloy material has the advantages that the coefficient of thermal expansion is close to that of ceramic; and under a high-power high-temperature work environment, the deformation of each terminal and the deformation of a ceramic dielectric medium block are relatively synchronized so that the connection of each terminal and the ceramic dielectric medium block is unlikely to be influenced.
Description
Technical field
The present invention relates to a kind of high-power high spacer medium duplexer, belong to the duplexer field.
Background technology
Duplexer claims again antenna multicoupler, is more special two-way three end filters.Duplexer transmits and is operated in a frequency, and acknowledge(ment) signal is operated in another frequency.Transmit and receive and share an antenna.Existing dielectric duplexer has the single electrolyte blocks that is made of pottery, offers a plurality of through holes at this electrolyte blocks, all is formed with simultaneously the conductor layer that silver consists of at front, side, the inside and the back side of this electrolyte blocks.And form the antenna terminal that is fit to connect antenna, the emission terminal and the reception terminal that is connected connect receiving circuit that is fit to connect radiating circuit by the part of this conductor layer.Between antenna terminal and emission terminal, consist of the resonance filter of emission, between antenna terminal and reception terminal, consist of the resonance filter that receives.Along with the technical development of the communications industry, require microwave diplexer to possess simultaneously microwave diplexer lightweight, high-power, that capability of electromagnetic shielding is good.
The reception terminal of existing dielectric duplexer and emission terminal adopt Surface Mount form and external circuit coupling mostly, and under the high power work condition, the surface-mount type coupling can produce a large amount of heats because contact resistance is larger.These heats are assembled at the terminal place and are caused temperature to rise, the easy Yin Gaowen of polytetrafluoroethylene of terminal periphery insulation usefulness and the phenomenons such as cracking affect insulation effect.
Duplexer also is welded with metal shielding by tin cream outward in the prior art, and to realize good capability of electromagnetic shielding, metal shielding uses metallic copper to make usually.Under the high power work condition, the working temperature of duplexer is higher, because copper is larger with the coefficient of thermal expansion gap of pottery, the tin cream that is connected usefulness between copper and the pottery can be torn, and affects the normal operation of duplexer.
Summary of the invention
Goal of the invention: the present invention proposes a kind of high-power high spacer medium duplexer, can adapt to powerful operational environment.
Technical scheme: the technical solution used in the present invention is a kind of high-power high spacer medium duplexer, it comprises that there is conductor layer on the surface, inside offers the electrolyte blocks of resonant cavity, it is characterized in that: the entity part at described electrolyte blocks front surface is provided with antenna terminal, receive terminal and emission terminal, electrolyte blocks is by the metal shielding parcel of iron-nickel alloy, and described emission terminal, antenna terminal and reception terminal all use the pin type pin, and described pin type pin is made by iron-nickel alloy.This pin type pin hole by offering at electrolyte blocks is inserted in the electrolyte blocks, and by described conductor layer parcel, realization is fixedly connected with electrolyte blocks.
Described pin type pin and metal shielding all use iron-nickel alloy to make.The chemical composition of this iron-nickel alloy is made of following composition:
Nickel 36～36.8%
Silicon 0.05～0.12%
Calcium 0.0005～0.0015%
Magnesium 0.0004～0.0018%
Carbon 0.002～0.004%
Surplus is iron.
Under the high operational environment of high-power temperature, above-mentioned iron-nickel alloy is comparatively approaching with the coefficient of thermal expansion of pottery, is difficult for occuring serious relative deformation.
Beneficial effect: the present invention will launch terminal, reception terminal and antenna terminal and move on in resonant cavity outside the resonant cavity, save the polytetrafluoroethylene that connects in the existing duplexer between resonant cavity and each terminal.Emission terminal, reception terminal, antenna terminal and metal shielding all use the iron-nickel alloy material to make.Iron-nickel alloy has the coefficient of thermal expansion that approaches with pottery with respect to existing metallic copper.In the high operational environment of high-power temperature, each terminal and metal shielding, relative with the deformation between the ceramic dielectric piece synchronous, so that the tin cream of connection metal shielding case and ceramic dielectric piece can not be torn, being connected between each terminal and the electrolyte blocks is also more stable.
