Abstract

The invention discloses a microwave frequency conversion power division circuit, which comprises a first intermediate frequency amplifier circuit, a second intermediate frequency amplifier circuit and a switching circuit. The first intermediate frequency amplifier circuit is used to pass a first polarity signal through a first frequency mixing circuit. The obtained intermediate frequency signal is amplified, and the second intermediate frequency amplifying circuit is used to amplify the intermediate frequency signal obtained after the second polarity signal passes through the second mixing circuit, and the switching circuit is respectively connected with the first intermediate frequency amplifying circuit and the second The intermediate frequency amplifying circuit is connected to switch and output the required frequency band signal, and the first intermediate frequency amplifying circuit and the second intermediate frequency amplifying circuit are designed symmetrically. The present invention realizes Ku-band full-band reception, and the symmetrical design of the first intermediate frequency amplifying circuit and the second intermediate frequency amplifying circuit reduces the power distribution point of the circuit, avoids the different lengths of the output signal lines, and reduces the loss of the power distribution line. The power amplification components are matched uniformly, and the circuit layout is simple and clear, easy to analyze, and high in reliability.

Description

technical field [0001] The invention relates to the technical field of microwave frequency conversion, in particular to a microwave frequency conversion power dividing circuit. Background technique [0002] With the rapid development of electronic technology, more and more manufacturers in the microwave communication industry use frequency converters to realize microwave signal processing. However, the design of the existing microwave frequency conversion power division circuit, especially the design of the intermediate frequency amplifier circuit, has an larger. Due to the different lengths of the output signal lines and the large number of signal dispersion points, the loss of the power distribution line is relatively large, and the matching of the power amplifier components is not uniform. Contents of the invention [0003] The invention provides a microwave frequency conversion power division circuit, which solves the technical problems of large line loss and non-unif...
