Description
Technical field
The utility model relates to electronic communication field, particularly a kind of L-band miniaturization frequency agility assembly for identification and electronic countermeasures.
Background technology
L-band miniaturization frequency agility assembly is mainly used in identification and electronic countermeasures.
Existing L-band frequency agility technology adopts mixing or the output of frequency multiplication link, and mainly below existence, some is not enough:
1) huge, the function singleness of small product size;
2) the auxiliary circuit quantity of using is more, and tie point each other increases, and has increased debugging difficulty, reliability is relatively low, is not easy to a large amount of production;
3) power consumption is large, index is poor.
Summary of the invention
The utility model is intended to solve existing L-band miniaturization frequency agility subassembly product the technical problems such as the large and index of bulky, function singleness, power consumption is poor, the L-band miniaturization frequency agility assembly that a kind of volume is very little to provide, circuit is relatively simple, debugging difficulty is low and reliability is relatively high is provided.
The purpose of this utility model is achieved through the following technical solutions.
L-band miniaturization frequency agility assembly of the present utility model, the first input end linking number word clock 1 of digital processing element 3, its second input connects external control signal, its the 3rd input connects the first output of digital synthesis unit 4, the output of digital processing element 3 connects the first input end of digital synthesis unit 4, the output of reference source 2 connects the second input of digital synthesis unit 4, and the second output of digital synthesis unit 4 connects amplifying unit 5 and the backward outer output frequency agility signal of filter cell 6 in turn.
The beneficial effect of the utility model L-band miniaturization frequency agility assembly: adopt Direct Digital, volume is very little, and circuit is relatively simple, and debugging difficulty is low, and reliability is relatively high, is more conducive to design and produces.
