Embodiment
Below in conjunction with accompanying drawing, the embodiment of the invention is elaborated.
Extremely shown in Figure 6 like Fig. 1; The double-sided copper-clad printed wiring board 1, the frame that are used to mainly the comprising of the wideband mixer of first embodiment of the invention to work in the system of two kinds of mutually noninterferes 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 the metal edge frame 2 in printed wiring board 1 a relative side cover, 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 combining with metallization groove 4 through angle 5 and welding;
Printed wiring board 1 comprises input port 9 and two delivery outlets, i.e. first delivery outlet 10 and second delivery outlet 11, and adopt base drive, the sense of current that promptly inputs or outputs signal be perpendicular to printed wiring board 1, sealing around the metal edge frame 2 simultaneously.When 9 inputs during broadband signals from the input port, first delivery outlet 10 and the irrelevant narrow band signal of second delivery outlet, 11 output two-way, and first delivery outlet, 10 output low frequency signals, second delivery outlet, 11 output high-frequency signals, two-way output Signal Spacing degree is less than-32dB; Otherwise, when from first delivery outlet 10 and second delivery outlet 11 input two-way narrow band signals, input port 9 outputs one band signal of having a lot of social connections.
Above-mentioned wideband mixer is when making; Metal edge frame 2 combines with the metallization groove 4 of printed wiring board 1 through the angle 5 on bottom sides edge earlier;, directly over printed substrate 1, through metallic tin both are welded as a whole again with location metal edge frame 2, on metal edge frame 2, cover metal cover board 3 at last; And the boss 8 of metal cover board 3 and the circular hole 6 of metal edge frame 2 fix through adhesion, can make things convenient for dismounting from now on to safeguard.
Aspect electrical property; The printed wiring board 1 of above-mentioned wideband mixer works in two kinds of systems that radio frequency signal frequency is respectively 1880-2025MHz and 2500-2690MHz; And when frequency was less than or equal to 2.7GHz, wideband mixer band is outer to be suppressed to insert loss less than 0.45dB less than-32dB.
Like Fig. 7 and shown in Figure 8; The wideband mixer of second embodiment of the invention and first embodiment distinguish mainly and are, printed wiring board 1 employing side feed, at this moment; Metal edge frame 2 offers the through hole 12 with the port number connecting line corresponding, that be used for ccontaining port of printed wiring board 1; In first embodiment, printed wiring board 1 comprises the input port 9 that can link to each other with the antenna output end mouth, and first delivery outlet 10 and second delivery outlet 11 that can link to each other with two ports of antenna different frequency bands; Corresponding, the number of through hole 12 is 3 and respectively corresponding input port 9, first delivery outlet 10 and second delivery outlet 11.Through hole 12 can be illustrated semicircle or rectangle, thereby passes through the setting of through hole 12, and the port of printed wiring board 1 can carry out cascade through connecting line and other circuit, has strengthened the application of wideband mixer.
As shown in Figure 9; The wideband mixer of third embodiment of the invention and first embodiment distinguish mainly and are; For total port number is doubled, be arranged side by side two printed wiring boards 1 in the wideband mixer, and two printed wiring board 1 integrated machine-shapings are with convenient processing and operation; Metal edge frame 2 is provided with the metal spacing block 13 that highly is equal to or less than metal edge frame 2 height between printed wiring board 1, can reduce the isolation between same port like this.
As a kind of execution mode, printed wiring board 1 can also work in the system of 3 kinds or more kinds of mutually noninterferes, and simultaneously, port number also can the corresponding increase along with the increase of corresponding frequency band quantity.
As a kind of execution mode, printed wiring board 1 and the combination of metal edge frame 2 are not limited only to the mode of above-mentioned fluting location welding, can also screw togather or mode such as bonding is accomplished combination through the corner.
As a kind of execution mode, metal edge frame 2 and the combination of metal cover board 3 are not limited only to the mode of above-mentioned circular hole boss assembling, can also accomplish through modes such as buckle and bayonet socket assemblings to combine.
The above is an embodiment of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also are regarded as protection scope of the present invention.
