Abstract
The utility model provides a loading structure for narrow band waveguide coupler, comprising a coaxial waveguide conversion apparatus and a fifty ohmic resistance; wherein, one end of the fifty ohmic resistance is connected with a central contact pin of the connector, and the other end is connected with a flange of the connector. In the utility model, the frequently used absorbing load of the general waveguide coupler isolation end is replaced by the matching of the general coaxial waveguide conversion apparatus and the fifty ohmic resistance, thus the utility model has the advantages that good electrical properties testing results can be obtained in the conditions of low cost and compact size through actual test.
Description
Technical field
The utility model relates to a kind of waveguide coupler support structures.
Background technology
For general coupler load, mostly utilize absorbing load to sponge the isolation end dump energy, absorbing load is shown in Fig. 1 dash area, volume is big, and assimilation effect is poor, still has unnecessary energy not absorb fully, exert an influence to isolating index, can not satisfy actual needs.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of arrowband waveguide coupler support structures is provided, and cost is low under the situation of same electrical property, and volume is little.
The technical solution of the utility model is: a kind of arrowband waveguide coupler support structures, comprise waveguide commentaries on classics coaxial device and 50 Ohmic resistances, and wherein 50 Ohmic resistances, one end is connected with connector center contact pin, and an other end is connected with adapter flange.
The utility model changes coaxial device with general common waveguide and cooperates with 50 Ohmic resistances, substitutes the absorbing load that general waveguide coupler isolation end is used always, tests by reality, in low cost, has obtained the good electrical properties test result under the little situation of volume.
Description of drawings
Fig. 1 is general coupler isolated port load common structure schematic diagram.
Fig. 2 is the utility model isolated port support structures schematic diagram.
Fig. 3 is 50 Ohmic resistance annexation schematic diagrames.
Fig. 4 is that the coaxial device structural representation is changeed in the waveguide of an embodiment of the utility model.
Embodiment
As shown in Figures 2 and 3, waveguide of the present utility model is changeed coaxial device and is comprised ring flange 1, contact pin 2, contact pin 3, the step 4 of connector 6 and beneath coupling, the welding of 50 Ohmic resistances 7 is welded resistance 7 one ends and connector 6 center contact pins as shown in Figure 3, an other end and adapter flange 1 welding.
The utility model is tested a kind of arrowband coupler of 7G frequency band, and index is as follows:
Frequency: 7.1-8.5GHz
Coupling: 6dB
Directivity: 25dB
Manufacture method, general by independent emulation, set up a waveguide and change the coaxial device model, port return loss is got final product less than 25DB, then by carrying out whole emulation with the coupler model, contact pin length and position that the inside SMA connector 6 of coaxial device is changeed in the debugging waveguide make to reach requirement on electric performance.Connector in the present embodiment need and producer special customized, its connector construction drawing comprises ring flange 1, passes medium 5, contact pin 2, the contact pin 3 of wave guide wall, the step 4 of beneath coupling as shown in Figure 4.In the present embodiment, utilize HFSS emulation, having obtained contact pin is 7.4mm apart from the position of waveguide short face, and the length H1 of contact pin 2 is 3mm, and diameter is connector inner wire diameter 1.3mm, and the length H2 of contact pin 3 is 2.5mm, and diameter is 4.2mm; Step 4 length of beneath coupling are 14.8mm, wide 3mm, high 3mm.By processing test, in this frequency band build-in test return loss greater than 25DB.
By emulation and actual test, emulation be coupled as 5.9dB+/-0.2dB, actual test for 6.2dB+/-0.15dB, directivity emulation be＞26dB that actual test is＞25.6dB that measured result and simulation theory value are approaching, have proved that the method is feasible.Again a kind of arrowband coupler of 15G frequency band has been carried out emulation and test then, proved that this device can be used in the microwave whole frequency band.
