Description
Technical field
The utility model relates to a kind of coupler, especially relates to a kind of strong coupling device with air chamber.
Background technology
In modern microwave millimeter-wave systems, coupler is one of vitals, for channel signal, distributes, and the quality of its performance directly affects the quality of whole communication system.Therefore in various microwave and millimeter wave systems, be widely used.
Traditional 6dB microstrip coupler is realized coupled modes and is adopted micro-band strip lines configuration and microstrip line gap coupled modes.
For example 6dB microstrip coupler adopts micro-band strip lines configuration can realize strong 6dB coupled structure, but require the necessary filled media of whole signal transmission space, first can cause cost waste, if second be arranged on and need to do integral united test in system and remove to mate other device, will be difficult to operation.As adopting microstrip line gap coupled modes to remove to realize 6dB, the gap between two coupling gaps only has 0.01mm, in reality, in processing, cannot realize at all.
Utility model content
The purpose of this utility model is exactly to provide a kind of strong coupling device with air chamber in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of strong coupling device with air chamber, comprise air cavity and pcb board, described air cavity comprises front air chamber and the reverse side air chamber being arranged on pcb board, it is characterized in that, described pcb board front is provided with the first transmission line, the 3rd transmission line and pcb board through hole, described pcb board reverse side is provided with the second transmission line, and the first described transmission line coupled section, pcb board through hole and the second transmission line form coupled zone.
The first described transmission line is connected with the first output port with first input end mouth respectively.
The second described transmission line two ends are connected with load port with the 3rd transmission line through 2 pcb board through holes respectively, and the 3rd described transmission line is connected with the second output port.
Described front air chamber, the first transmission line and the 3rd transmission line, pcb board, the second transmission line, and reverse side air chamber sets gradually from top to bottom, forms five-layer structure.
Compared with prior art, the utlity model has following advantage:
One, by of the present utility model, be micro-ly with two-sided coupling technique easily to realize 6dB to be coupled, and easily plate-making processing.
While two, coupler being assemblied in complete machine link, because the transmission of coupler signal is in front, can easily by pruning transmission line 1, realize the debugging of complete machine return loss.And can, by pruning the width of the positive transmission line 1 of coupling regime, realize the fine setting of the degree of coupling.
Accompanying drawing explanation
Fig. 1 is the structural representation of facing of the present utility model;
Fig. 2 is left TV structure schematic diagram of the present utility model;
Wherein, 1 is that front air chamber, 2 is that reverse side air chamber, 3 is that the first transmission line, 4 is that the second transmission line, 5 is that the 3rd transmission line, 6 is that first input end mouth, 7 is that the first output port, 8 is that the second output port, 9 is load port, A is coupling regime, and B is pcb board.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment 1:
As depicted in figs. 1 and 2, in figure, be a 6dB microstrip coupler structure, whole coupler structure is divided into 5 layers of structure, front air chamber 1, the first transmission line 3, the second transmission line 4, medium pcb board, the 3rd transmission line 5, reverse side air chamber 2.Microwave radio signal is transferred to the first output port 7 outputs from 6 inputs of first input end mouth by the first transmission line 3.At coupling regime, by the second transmission line 4 and the first transmission line 1, produce signal coupling.The signal of coupling is exported from the second output port 8 through the 3rd transmission line 5 to front through the through hole of medium pcb board again, and load port 9 connects matched load, thereby realizes close coupling process.
With a 850MHz coupled example.Frequency microwave signal, from the input of input sub-miniature A connector, outputs to output sub-miniature A connector by main transmission line, and reverse side coupled microstrip line is realized 6dB coupling and outputed to coupling sub-miniature A connector coupling output by coupled transmission line.
