Background technology
Domestic present power splitter is mainly microstrip power divider and cavity power splitter; And frequency range nearly all is 800-2500MHz, and along with the arrival of 3G, we will be in the face of the 4G epoch in the near future; And 4G need use 2500-2700MHz, and product in the market can not satisfy the demands.Therefore need the cavity power splitter product of the 800-2700MHz of a function admirable of design badly, be applied to the pilot function of 4G, and the construction that in the future is used for the 4G epoch.This patent design realizes that in the 800-2700MHz frequency range standing wave is less than 1.3 matched well effect; This patent sound construction, dependable performance, high power capacity, easy for installation, cost is extremely low, and the very strong market competitiveness is arranged.
The utility model content
Technical problem to be solved: provide a kind of differential loss low to above problem the utility model, matched, sound construction,
Dependable performance, high power capacity, easy for installation, cavity three power splitters that cost is extremely low towards 4G.
Technical scheme: the utility model is realized through following technical scheme: a kind of cavity three power splitters towards 4G; Comprise merit branch rod, power splitter shell, power splitter out splice going splice, power splitter input adapter; Merit divides excellent two ends to link to each other with the power splitter input adapter with the power splitter out splice going splice respectively, and the power splitter shell is arranged on merit and divides outside the rod; It is characterized in that: merit divides rod to adopt five joint impedance conversion joints.
Said merit divides rod to comprise merit branch rod one, merit branch rod two; Merit divides rod to hold one by one to be connected with three power splitter out splice going splices, and the other end divides rod two to link to each other with merit, and merit divides excellent two the other end to link to each other with the power splitter input adapter.
Said power splitter out splice going splice is three.
It is that internal thread and merit divide rod two to be external screw thread that described merit is divided rod one, divides rod one 1 screw thread places to be provided with steam vent 6 in merit.
Described merit divides rod one and merit to divide rod two surfaces silver coated.
Described merit divides rod one and merit to divide rod two to be connected for the screw thread tight fit.
Beneficial effect: the structural design of the utility model can satisfy the frequency needs in the 4G epoch of 800-2700MHz, and this design differential loss is low simultaneously, match, and sound construction, dependable performance, high power capacity, easy for installation, cost is extremely low, and the very strong market competitiveness is arranged.

Embodiment
A kind of cavity three power splitters towards 4G comprise merit branch rod, power splitter shell 3, power splitter out splice going splice 4, merit branch
Device input adapter 5; Merit divides excellent two ends to link to each other with power splitter input adapter 5 with power splitter out splice going splice 4 respectively, and power splitter shell 3 is arranged on merit and divides outside the rod; Merit divides rod to comprise merit branch rod 1, merit branch rod 22; Merit divides rod one 1 one ends to be connected with three power splitter out splice going splices 4, and the other end divides rod 22 to link to each other with merit; Merit divides the other end of rod 22 to link to each other with power splitter input adapter 5.
When receiving signal, the feeder line of indoor covering is connected to power splitter input adapter 5, divides rod 22 and merit to divide rod 1 to be connected to power splitter out splice going splice 4 through merit, realizes the power trisection of frequency signal, is connected respectively on three antennas to external radiation.
Merit divides rod 1 and merit to divide rod 22 usefulness five joint impedance conversion joints to realize the design of wideband; This design has guaranteed the design of 800-2700MHz wideband, has increased the frequency range of 200MHz than the present product of 800-2500MHz on the market.And guaranteed standing-wave ratio in the full range scope, realized good matching effect less than 1.3.
Merit branch rod 1 divides the processing of rod 22 electroplates to realize the insertion loss less than 0.2dB with merit.
Merit divides rod 1 and merit to divide rod 22 to adopt the screw thread tight fit to be connected.The convenient installation more conveniently helps improving machining accuracy,
Enhance product performance.Principle: owing to all possibly bring the index performance significantly to reduce, become five joint impedance conversion joint splits two merits to divide rod to be threaded, realize better dimensional accuracy when helping Vehicle Processing, improve concentricity, reduce error in the very little mismachining tolerance of high band; If the merit of one five joint of whole processing impedance conversion divides rod to be difficult to reach the machining accuracy of 0.02mm.
It is that internal thread divides rod 22 to be external screw thread with merit that merit is divided rod 1, divides rod one 1 screw thread places to be provided with steam vent 6 in merit, makes merit divide that rod 1 and merit branch excellent 22 are more convenient to be connected with the screw thread tight fit.Principle: merit can be because the problem of the pressure of air be difficult to be screwed into when dividing rod 22 to divide one 1 li of rods to be screwed into toward merit, and the processing steam vent has solved this problem fully.
