Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is elaborated.
As shown in Figures 1 to 6, mainly comprise double-sided copper-clad printed wiring board 1, the frame for working in two kinds of non-interference systems of the broadband combiner of first embodiment of the invention are located at the metal edge frame 2 of these printed wiring board 1 one sides, and be located at the metal cover board 3 on metal edge frame 2 in the relative side cover of printed wiring board 1, wherein:
The upper surface edge of printed wiring board 1 offers metallization groove 4, and the bottom sides of metal edge frame 2 is along being combined and weld with metallization groove 4 by angle 5;
Printed wiring board 1 comprises input port 9 and two delivery outlets, i.e. the first delivery outlet 10 and the second delivery outlet 11, and adopt base drive, input or output the sense of current of signal perpendicular to printed wiring board 1, metal edge frame 2 surrounding sealings simultaneously.In the time inputting broadband signal from input port 9, the first delivery outlet 10 and the second delivery outlet 11 are exported the irrelevant narrow band signal of two-way, and the first delivery outlet 10 output low frequency signals, the second delivery outlet 11 is exported high-frequency signal, be less than-32dB of two-way output signal isolation; Otherwise in the time inputting two-way narrow band signal from the first delivery outlet 10 and the second delivery outlet 11, the band signal of having a lot of social connections is exported in input port 9.
Above-mentioned broadband combiner is in the time making, metal edge frame 2 first combines by the angle 5 on bottom sides edge and the metallization groove 4 of printed wiring board 1, with positioning metal frame 2 directly over printed substrate 1, by metallic tin, both are welded as a whole again, finally on metal edge frame 2, cover metal cover board 3, and the boss 8 of metal cover board 3 fixes by adhesion with the circular hole 6 of metal edge frame 2, can facilitate dismounting from now on to safeguard.
Aspect electrical property, the printed wiring board 1 of above-mentioned broadband combiner works in radio frequency signal frequency and is respectively two kinds of systems of 1880-2025MHz and 2500-2690MHz, and in the time that frequency is less than or equal to 2.7GHz, be less than-32dB of broadband combiner Out-of-band rejection, insertion loss is less than 0.45dB.
As shown in Figures 7 and 8, the broadband combiner of second embodiment of the invention and the first embodiment distinguish mainly and are, printed wiring board 1 adopts side feed, now, metal edge frame 2 offers corresponding with the port number of printed wiring board 1, be used for the through hole 12 of the connecting line of accommodating port, in the first embodiment, printed wiring board 1 comprises the input port 9 that can be connected with antenna output end mouth, and first delivery outlet 10 that can be connected with two of an antenna different frequency bands port and the second delivery outlet 11, corresponding, the number of through hole 12 is 3 and corresponding input port 9 respectively, the first delivery outlet 10 and the second delivery outlet 11.Through hole 12 can be illustrated semicircle or rectangle, thereby by the setting of through hole 12, the port of printed wiring board 1 can carry out cascade by connecting line and other circuit, has strengthened the application of broadband combiner.
