Abstract
Frequency hopping communication, as one of the main methods in the field of modern wireless communication, has the advantages of strong anti-interference ability, low interception probability, and excellent multiple access networking capabilities. However, in the modern information battlefield, the relatively complex electromagnetic environment composed of various electromagnetic elements is becoming more and more serious to the wireless system. In order to further improve the anti-interference performance of frequency hopping communication equipment, increasing the communication bandwidth and frequency hopping rate is an inevitable way for the development of frequency hopping communication. As an important part of the frequency hopping communication front end, the up-down conversion module plays a vital role in the performance of the frequency hopping communication system. This article introduces in detail the design and implementation of the Ka-band upconversion module based on the fast frequency hopping system, and analyzes and researches the scheme design and index analysis of the up-conversion unit, down-conversion unit and ping-pong frequency source in the module.
