X wav band frequency conversion assembly

Abstract

The present invention provides an X waveband frequency conversion assembly. The assembly includes: a first frequency multiplier, a first mixer, a first filtering amplifier, a second mixer, a second filtering amplifier, a first frequency divider, a third mixer, a third filtering amplifier, a first power divider, a second power divider, a second frequency multiplier and a second frequency divider, wherein the input end of the first frequency multiplier receives an intermediate frequency signal; the input end of the first power divider receives a high frequency local oscillator signal; an output end of the first frequency multiplier is connected to the input end of the third filtering amplifier sequentially via the first mixer, the first filtering amplifier, the second mixer, the second filtering amplifier, the first frequency divider and the third mixer; the output end of the first power divider is divided into two paths, one path is directly connected to the first mixer, while the other path is connected to the second power divider; and the output end of the second power divider is divided into two paths, one path is connected to the second mixer via the second frequency multiplier, while the other path is connected to the third mixer via the second frequency divider. The X waveband frequency conversion assembly of the present invention can increase frequency conversion stability.

Description

technical field [0001] The invention relates to the technical field of frequency conversion, in particular to an X-band frequency conversion component. Background technique [0002] With the development of microwave electronic technology, especially the rapid development of communication and radar technology, the management of spectrum resources is becoming more and more strict, and the frequency conversion technology has made breakthroughs every day. So far, there are many design schemes for frequency converters, but these schemes usually mix the intermediate frequency signal directly with the high frequency local oscillator signal. However, the direct mixing of the intermediate frequency signal with the high frequency local oscillator signal often makes the filter It cannot be realized, resulting in poor frequency conversion stability. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an X-band frequency conver...
