Ka frequency band transmitter based on frequency synthesizer mobility and implementation method thereof

Abstract

The invention discloses a Ka frequency band transmitter based on frequency synthesizer mobility and an implementation method thereof. The Ka frequency band transmitter comprises a secondary frequencyconversion module which is used for carrying out the frequency conversion of an inputted first signal; a microwave driving module which is used for amplifying and filtering the second signal; a final-stage space power synthesis module which is used for carrying out power amplification on the third signal in a mode of combining space power synthesis and waveguide power division synthesis; a coupling detection module which is used for coupling and detecting the fourth signal. According to the transmitter and the method disclosed in the invention, a secondary frequency conversion technology basedon frequency synthesizer mobility is added in a frequency conversion link in a traditional method, and a combined technology of space power synthesis and waveguide power division synthesis is used ina power synthesis link, and therefore the technical effect that the transmitter can be suitable for a Ka frequency band full frequency band without customization is realized; the power synthesis efficiency of the transmitter is effectively improved, and therefore the Ka frequency band transmitter can be suitable for more application scenes.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a Ka-band transmitter based on a movable frequency synthesis and an implementation method thereof. Background technique [0002] With the rapid development of high-throughput satellite mobile communication technology in the field of satellite communication in recent years, the Ka frequency band has been widely developed and utilized, and has become one of the main frequency bands for future high-throughput communication applications. However, due to the overall wide frequency band of the Ka frequency band, the frequency band occupied by the application field is only a part of it. In the case of the same intermediate frequency input, the output frequency bands of millimeter waves are different due to different application channels, which often lead to incompatibility between them. [0003] For the current Ka-band transmitter, the traditional method is to fix a loca...
