Abstract
A passive power distributor comprises a lambda/4-stepped impedance transformer and a casing. The stepped impedance transformer is arranged inside the casing and is of a copper axial conductor, a medium layer is arranged between the stepped impedance transformer and the casing, and the space between the casing and the stepped impedance transformer is filled by the medium layer. Polytetrafluoroethylene is filled into the copper axial conductor and the casing to form the medium layer to shorten transmission wavelength, so that in design process, the length of the stepped impedance transformer can be shortened to reduce manufacturing cost, and processing difficulty can be reduced by adopting a medium filling method.
Description
Technical field
The utility model belongs to microwave device, is used for the system of microwave internal home network coverings such as GSM CDMA TD-SCDMA, is a kind of passive cavity power divider.
Background technology
The passive cavity power divider has obtained a large amount of uses in internal home network covers, in antenna-feedback system, it is the parts of a key, and requires loss low, bandwidth.Cavity power divider commonly used, microwave is propagated in air, because aerial wavelength is bigger, so that the chamber power divider volume of working it out all compares is big, is difficult to reduce cost; Though utilize microstrip line can produce the little wide band power divider of size, but have the loss height, machining accuracy is high and be difficult for shortcoming such as processing.
Summary of the invention
Problem to be solved in the utility model is: existing Passive Power distributor volume is bigger, and cost is difficult to descend, and the loss height is difficult for processing.
The technical solution of the utility model is: the passive cavity power divider, comprise λ/4 stepped impedance transformers and housing, stepped impedance transformer is arranged in the housing, stepped impedance transformer is a copper axis conductor, be provided with the solid dielectric layer between stepped impedance transformer and the housing, the solid dielectric layer is filled the space between housing and the stepped impedance transformer.
Preferably, the solid dielectric layer is a polytetrafluoroethylene.
The utility model injects polytetrafluoroethylene in copper axis conductor and housing, form the solid dielectric layer, transmission wavelength is shortened, and then make in the design process, the length of stepped impedance transformer can shorten, thereby the minimizing cost of manufacture adopts the method that is cast into medium can reduce cost and technology difficulty.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model power divider adopts copper axis designs method, use 1/4 wavelength, as Fig. 1, comprise λ/4 stepped impedance transformers 3 and housing 2, stepped impedance transformer 3 is arranged in the housing 2, stepped impedance transformer 3 is a copper axis conductor, is provided with solid dielectric layer 1 between stepped impedance transformer 3 and the housing 2, the space that solid dielectric layer 1 is filled between housing 2 and the stepped impedance transformer 3.
The utility model utilizes wavelength characteristics than airborne wavelength weak point in solid dielectric, in copper axis conductor and housing 2, inject polytetrafluoroethylene, form solid dielectric layer 1, transmission wavelength is shortened, and then the physics actual size of 1/4 wavelength of each joint of minimizing stepped impedance transformer, thereby the minimizing cost of manufacture, and adopt the method that is cast into medium can also reduce technology difficulty.
