X-band frequency converter

Abstract

The invention provides an X-band frequency converter. The X-band frequency converter comprises a first frequency multiplier, a first frequency mixer, a first filter amplifier, a first frequency divider, a second frequency mixer, a second filter amplifier, a third frequency mixer, a third filter amplifier, a first power divider, a second power divider and a second frequency divider, wherein the input end of the first frequency multiplier is used for receiving an intermediate-frequency signal; the input end of the first power divider is used for receiving a high-frequency intrinsic signal; the output end of the first frequency multiplier is connected with the input end of the third filter amplifier after passing through the first frequency mixer, the first filter amplifier, the first frequency divider, the second frequency mixer, the second filter amplifier and the third frequency mixer in sequence; the output end of the first power divider is divided into two paths; one path is directly connected with the first frequency mixer, and the other path is connected with the second power divider; the output end of the second power divider is divided into two path; and one path is directly connected to the second frequency mixer, and the other path is connected with the third frequency mixer through the second frequency divider. Through adoption of the X-band frequency converter, the frequency conversion stability can be enhanced

Description

technical field [0001] The invention relates to the technical field of frequency conversion, in particular to an X-band frequency converter. 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 converter, which ...
