In system, effect is that microwave power all the way is divided into multiple-channel output by a certain percentage, generally with micro-strip function from the point of view of transmission line
Divide based on device and coaxial cavity power divider.In order to realize the application in broadband or ultra-wideband communications, power splitter is mostly become with multistage impedance
The mode of changing occurs.Coaxial line chamber power divider can bear big power, and current design method is all using 1/4 wavelength come real
Existing, the length of power splitter is very long, causes cost excessively high.Since output end is short-circuit condition, so output end does not have isolation to refer to
Mark exists.In view of the requirement to output end isolation, some scenes must use microstrip power divider.Existing microstrip power divider is universal
Conventional sugarcoated haws structure design is selected, circuit layer is complex curve, because of incoherence caused by route shape, product index
Unstable, intermodulation reduces, and the wider width of calabash shaped structure, brings the uncontrollability of assembly.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of scalariform microstrip power divider, no complex curve, avoid because
Incoherence caused by route shape, reduces the non-linearity of circuit, and product index is stablized.
The technical solution of the utility model are as follows:
A kind of scalariform microstrip power divider includes cavity, is fixed on the intracorporal microstripline plate of chamber and is fixed on cavity
And the connector connecting with microstripline plate, the microstripline plate include insulation medium board, are set to insulation medium board
On scalariform micro-strip, the scalariform micro-strip include the microstripline layer being fixed on insulation medium board upper surface and it is multiple every
From resistance, the microstripline layer is U-shaped microstrip structure, the bottom end of microstripline layer i.e. its input terminal and cavity input end
Connector connection, two tops of microstripline layer i.e. its two output end is corresponding with the connector of two outputs of cavity respectively
Connection, so that microstripline layer be made to form two function point micro-strips, inner ring i.e. two function of the microstripline layer divides micro-strip
Inner side edge is straight line and is parallel to each other, and multiple isolation resistances are welded in the U-lag mouth of two function point micro-strips formation
And be distributed along the axial direction of cavity, the outer side edges of the outer ring i.e. two function point micro-strip of the microstripline layer are ladder bending
Line, and divide the input terminal of micro-strip to output end width segments to increase from function.
It is provided with multiple internal thread holes on the insulation medium board, multiple and interior spiral shell is provided on the cavity inner wall
The tapped blind hole of pit overlapping, multiple bolts be each passed through after corresponding inner bolt hole extend into corresponding tapped blind hole internal locking from
And insulation medium board is fixed in cavity.
Multiple internal thread holes on the insulation medium board are situated between adjacent to the edge of insulation medium board and along insulation
The periphery of scutum is uniformly distributed.
The output end of two function point micro-strips is to be directed toward the bending structure for being correspondingly connected with device.
The advantages of the utility model:
(1), the utility model structure is simple, no complex curve, avoid because route it is complex-shaped caused by incoherence, subtract
The non-linearity of few circuit, product index are stablized, and intermodulation are improved, convenient for the processing of product；
(2), the utility model because scalariform micro-strip overall width it is relatively narrow, the insulation medium board of microstripline plate is equal by bolt
It is even to be fixed in cavity, reduce assembly bring uncontrollable factor；
(3), the utility model greatly reduces the overall width of microstrip power divider, reduces processing cost, is suitable for big
Large-scale production processing.
