Description
Technical field
The present invention relates to converter technique field, particularly relate to a kind of X-band frequency conversion assembly.
Background technology
Along with the development of microwave electron technology, the especially fast development of communication, Radar Technology, more and more stricter to the management of frequency spectrum resource, converter technique breaks through in the daytime.Up to now; the design of frequency converter has a variety of, but these schemes are all that intermediate-freuqncy signal is direct and high-frequency local oscillation signal direct conversion usually, but; intermediate-freuqncy signal directly and the mixing of high-frequency local oscillation signal filter usually can be made to realize, cause frequency conversion poor stability.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of X-band frequency conversion assembly, can improve frequency conversion stability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of X-band frequency conversion assembly, comprise: the first frequency multiplier, first frequency mixer, first filter amplifier, second frequency mixer, second filter amplifier, first frequency divider, three-mixer, 3rd filter amplifier, first power splitter, second power splitter, second frequency multiplier and the second frequency divider, wherein, the input receiving intermediate frequency signal of described first frequency multiplier, the input of described first power splitter receives high-frequency local oscillation signal, the output of described first frequency multiplier is successively through the first frequency mixer, first filter amplifier, second frequency mixer, second filter amplifier, first frequency divider, after three-mixer, connect the input of the 3rd filter amplifier, the output of described first power splitter is divided into two-way, and a road directly connects the first frequency mixer, and another road connects the second power splitter, the output of described second power splitter is divided into two-way, and road second frequency multiplier connects the second frequency mixer, and another road second frequency divider connects three-mixer.
Be different from the situation of prior art, the invention has the beneficial effects as follows: utilize frequency multiplier by direct after intermediate-freuqncy signal frequency multiplication tremendously high frequency and high-frequency local oscillation signal mixing, by frequency division recovering signal when finally exporting, avoid the direct conversion of intermediate-freuqncy signal and high-frequency local oscillation signal and filter cannot be realized, thus frequency conversion stability can be improved.
Accompanying drawing explanation
Fig. 1 is the principle schematic of embodiment of the present invention X-band frequency conversion assembly.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the principle schematic of embodiment of the present invention X-band frequency conversion assembly.The X-band frequency conversion assembly of the present embodiment comprises the first frequency multiplier, the first frequency mixer, the first filter amplifier, the second frequency mixer, the second filter amplifier, the first frequency divider, the 3rd filter amplifier, three-mixer, the 4th filter amplifier, the first power splitter, the second power splitter, the second frequency multiplier and the second frequency divider.
Wherein, the input receiving intermediate frequency signal of the first frequency multiplier, the input of the first power splitter receives high-frequency local oscillation signal.
The output of the first frequency multiplier, successively after the first frequency mixer, the first filter amplifier, the second frequency mixer, the second filter amplifier, the first frequency divider, the 3rd filter amplifier, three-mixer, connects the input of the 4th filter amplifier.
The output of the first power splitter is divided into two-way, and a road directly connects the first frequency mixer, and another road connects the second power splitter; The output of the second power splitter is divided into two-way, and road second frequency multiplier connects the second frequency mixer, and another road second frequency divider connects three-mixer.
As shown in Figure 1, suppose that intermediate-freuqncy signal is F1, high-frequency local oscillation signal is that F7, intermediate-freuqncy signal F1 obtain signal F2=NF1 after frequency multiplication, so, in the first frequency mixer, first by signal F2 and the mixing of high-frequency local oscillation signal, then through the first filter amplifier filtering except after spuious, obtain signal F3=F7+NF1 in theory, signal NF7 after second frequency multiplier frequency multiplication and signal F3 mixing in the second frequency mixer, through the second filter amplifier filtering except after spuious, obtain signal F4=F7+NF7+NF1.Signal F4 obtains signal F5=F7/N+F7+F1 after frequency division in the first frequency divider.Signal F7/N after second frequency divider frequency division and signal F5 mixing in three-mixer, through the 3rd filter amplifier filtering except after spuious, obtain signal F6=F7+F1, thus achieve signal frequency conversion.In the present embodiment, be equipped with filter amplifier after each frequency mixer, object is the friendship intermodulation component of filtering mixing, improves clutter recognition.
The present invention utilizes the intermediate-freuqncy signal after frequency multiplication to come and the mixing of high-frequency local oscillation signal, avoids the direct conversion of intermediate-freuqncy signal and high-frequency local oscillation signal and filter cannot be realized, thus can improve frequency conversion stability.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
