But along with the development of mobile communications industry, band radio communication gets more and more, more and more wider, existing broadband power divider can not meet actual needs, there is passive intermodulation to worsen, preferably can only accomplish-135dBc, and intermodulation value can extend the technical problems such as degradation failure deterioration in time, how solve the problems of the technologies described above the direction becoming those skilled in the art and make great efforts.
Summary of the invention
The utility model provides a kind of microstrip power divider, and this microstrip power divider insertion loss is little, and isolation is high, and fluctuation range is little, and index is stablized, and reliability is high, and joint is flexible, is applicable to multiple frequency range.
For achieving the above object, the technical solution adopted in the utility model is: a kind of microstrip power divider, comprise: cavity box, microstripline plate and the cover plate being installed on cavity box end face, described cavity box one end is provided with input interface, the other end is provided with at least 2 output interfaces, described microstripline plate is installed on the cavity bottom of cavity box, the upper surface of described microstripline plate has at least 2 microstrip lines, article at least 2, described microstrip line is all electrically connected by wire with input interface one end separately, article at least 2, described microstrip line separately the other end be electrically connected by wire with at least 2 output interfaces respectively, described microstripline plate is installed with between cavity box be connected by plastics screw.
The technical scheme that technique scheme is improved further is as follows:
1. in such scheme, the center being positioned at described cavity box offers hollow-out parts, thus is positioned at hollow-out parts periphery forming station terrace bottom cavity box, and described microstripline plate is installed on the step surface of cavity box.
2., in such scheme, described plastics screw is distributed in the microstripline plate region of at least 2 microstrip line both sides.
3. in such scheme, described cavity box edge is circumferentially with waterproof groove along it, and the sealing ring by embedding waterproof groove between cavity box and cover plate is tightly connected.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model microstrip power divider, its insertion loss is little, and isolation is high, and fluctuation range is little, and index is stablized, and reliability is high, and joint is flexible, is applicable to multiple frequency range; Secondly, its microstripline plate is connected, because do not have magnetic material in plastics screw with being installed by plastics screw between cavity box, passive intermodulation is very helpful, preferably can accomplish-150dBc, and avoid the defect that intermodulation value can extend degradation failure deterioration in time, intermodulation is stable high;
2. the utility model microstrip power divider, its center being positioned at cavity box offers hollow-out parts, thus hollow-out parts periphery forming station terrace is positioned at bottom cavity box, microstripline plate is installed on the step surface of cavity box, both microstripline plate and cavity box contact area had been reduced, define gap again, contact area reduces to make the contact of microstripline plate and cavity large, is conducive to the stability of electrical property during high/low temperature; Secondly microstripline plate adopts the raw sheet of individual layer Copper Foil, and the face contacted with cavity box, without Copper Foil, reduces the cost of product.
