Description

The electric bridge module that is used for POI equipment

Technical field

The utility model relates to the electric bridge module in a kind of POI equipment, relates in particular to a kind of electric bridge module for POI equipment.

Background technology

Be provided with 3dB electric bridge module in the existing POI equipment, 3dB electric bridge module is used for the two-way input signal is closed road or along separate routes output; Existing 3dB electric bridge module volume is larger, is adding man-hour, and the requirement on machining accuracy of the internal structure of 3dB electric bridge module is very high, causes 3dB electric bridge module cost higher.

The utility model content

For the problem in the background technology, the utility model proposes a kind of electric bridge module for POI equipment, its structure is: it is comprised of paster electric bridge, PCB circuit board and cavity, the PCB circuit board is arranged in the cavity, microstrip line joint on the PCB circuit board is arranged at housing surface, the paster electric bridge is welded on the PCB circuit board, and the input of paster electric bridge, output are electrically connected with input, the output of microstrip line respectively.

After adopting aforementioned structure, can realize by paster electric bridge and PCB circuit board the function of existing 3dB electric bridge module, obviously, difficulty of processing of the present utility model is much lower, the utility model is to the almost no requirement (NR) of machining accuracy of internal components, only need unimpeded the getting final product of electrical connection between each device of assurance, it realizes simple, good stability.

When structure work of the present utility model was closed two application in two minutes two or two, the utility model has also proposed following preferred constructive form: described microstrip line is dual input, dual output pattern, be provided with 4 microstrip line joints on the housing surface, 4 microstrip line joints correspond respectively to two inputs and two outputs of microstrip line.

When structure of the present utility model is done the application of two-in-one or one-to-two, the utility model has also proposed following preferred constructive form: described microstrip line is single input, dual output pattern, be provided with 3 microstrip line joints on the housing surface, be provided with 50 ohm load on the PCB circuit board, input on the microstrip line is corresponding with the first output, input and the first output are corresponding one by one with the first microstrip line joint and the second microstrip line joint respectively, the second output on the microstrip line is corresponding with the 3rd microstrip line joint, and the second output also is electrically connected with 50 ohm load.

Useful technique effect of the present utility model is: simple in structure, and working stability, machining accuracy is low, and production efficiency is high, and volume is little.
