Abstract
The invention discloses the load of a kind of low intermodulation power, it is characterised in that include two fin, being provided with two insulation boards between two fin, be provided with microstrip line between two insulation boards, microstrip line is folded strip line, one end of microstrip line is input, and its other end is open end.The structure of the microstrip line in the present invention makes the whole external form of the present invention and spatially reduces a lot, and production cost is substantially reduced, it is adaptable to the mounting arrangement requirement of small space.Relative to the terminal matched load of traditional design, the present invention has been designed to open-end, it is not necessary to ceramic load, and on intermodulation substantially without producing impact, cost is substantially reduced.
Description
Technical field
The present invention relates to the load of a kind of low intermodulation power, belong to mobile communication equipment technical field.
Background technology
In communication aspects, traditional low intermodulation power load, is on the one hand all by method for winding system with coaxial cable
Becoming, this mode of production can bring a lot of problem: cable around when can cause the fracture on cable top layer, as pressed not
Tightly, radiating effect can be caused bad, laborious when also taking a lot of work, production cost is greatly increased, but the scrappage of final products also exists
Improve constantly, so coaxial cable Costco Wholesale in the market is bigger, do not have advantage to say；Second aspect is exactly that tradition sets
The terminal matched load of meter, uses ceramic material, price and also intermodulation can be produced, bring a lot of trouble to production.Along with shifting
Dynamic communication etc. are towards miniaturization, and the demand of different low intermodulation power load constantly increases, but is often touching in price
To bottleneck.
Summary of the invention
The technical problem to be solved in the present invention is: provides the low intermodulation power load of a kind of low cost, good heat dissipation, solves
The problem that radiating effect is bad in traditional low intermodulation power load, laborious when taking a lot of work, cost is big.
In order to solve above-mentioned technical problem, the technical scheme is that and provide the load of a kind of low intermodulation power, it is special
Levy and be, including two fin, be provided with two insulation boards between two fin, between two insulation boards, be provided with microstrip line,
Microstrip line is folded strip line, and one end of microstrip line is input, and its other end is open end.
Preferably, described insulation board is polyfluortetraethylene plate.
Preferably, described microstrip line is the titanium foil opening groove.
Good heat dissipation of the present invention, the structure of microstrip line therein makes the whole external form of the present invention and spatially reduces a lot,
Production cost is substantially reduced, it is adaptable to the mounting arrangement requirement of small space.Relative to the terminal matched load of traditional design, this
Invention has been designed to open-end, it is not necessary to ceramic load, and on intermodulation substantially without producing impact, cost is substantially reduced, suitable
In commercialization.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of low intermodulation power load；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural representation of microstrip line.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The present invention is mainly made up of microstrip line 3, insulation board 2, fin 1 and joint, and it uses one to open the titanium foil of groove (i.e.
Microstrip line 3), instead of traditional coaxial cable, be placed in up and down with between two insulation boards 2 and two fin 1, such as Fig. 1
Shown in, microstrip line 3 is folded strip line, and folded strip line one end is input 4, and its other end is the open end 5 of terminal.
Wherein, insulation board 2 is polyfluortetraethylene plate.
The produced intermodulation product of low intermodulation load of the present invention is less than-160dBc, and is dispelled the heat by fin 1.
The structure of the present invention makes whole external form and spatially reduces a lot, and production cost is substantially reduced, it is adaptable to narrow and small
The mounting arrangement requirement in space.This folded strip line can be processed by the technique of corrosion, and the time is fast, precision is high, be substantially reduced
Production cost.
