Description
Technical field
The utility model is related to coupler technologies field, specially a kind of directional coupler.
Background technology
Directional coupler is a kind of general microwave/millimeter wave part, isolation, separation and mixing available for signal, such as
Sweep check that the monitoring of power, source power output fixed ampllitude, signal source are isolated, transmit and reflected etc..The key technical indexes side of having
Tropism, standing-wave ratio, the degree of coupling, insertion loss.For distributing or synthesizing microwave signal power and there is the micro- of directional couple characteristic
Ripple element.It is to set what appropriate coupled structure was constituted between major and minor two transmission lines (referred to as major and minor line).Orient coupling
Clutch is using various types such as coaxial line, strip line, microstrip line, metal waveguide or Medium Wave Guides.Coupled structure has coupling aperture, coupling
Close the pattern such as branch line and continuous structure coupling.
Due to quickly growing for industry, it is divided into according to operator frequency difference, such as：698MHz -2700MHz, 800MHz -
2500MHz.Etc. the demand of frequency.Each frequency style and quality requirements are caused to differ.It is unified in order to meet operator needs and production
Change.The utility model directional coupler is drawn through design update.
Utility model content
The purpose of this utility model is to provide a kind of directional coupler, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of directional coupler, including cavity, institute
Cavity one end is stated provided with input port, the other end is provided with output port, and the cavity upper end is at input port provided with coupling
50 Ohmic resistances are installed, the cavity inner chamber is provided with inner wire curved rod and the straight rod of inner wire at end, the coupled end resistance terminal, and
The inner wire curved rod and the straight rod of inner wire are connected with input port, output port, coupled end.
It is preferred that, the input port, output port, coupled end are connector, and connector mounting hole is opened by mould
Go out one-shot forming；Connector size is 13.7*18mm N-types.
It is preferred that, in addition to medium strip, the medium strip setting two, it is placed in the middle of cavity, the medium strip size
For 2.1*2.1*26.5mm.
It is preferred that, the inner wire curved rod and the straight rod of inner wire are placed on inside cavity and alignd with connector pin.
Compared with prior art, the beneficial effects of the utility model are：
