Embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated to the utility model.
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 the utility model first embodiment 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.
