星载微波光子铌酸锂调制器变频技术研究

摘要

In this paper, the technical characteristics and the application background of microwave photonics frequency conversion were introduced. Several typical schemes were compared,the principle of frequency conversion based on series of LiNbO3 modulators was analyzed in detail, a new LN-MZ frequency conversion scheme was put forward, serials of system simulation was made. Essential theoretical basis and technical support were provided for new scheme of microwave photonics frequency conversion of satellite payloads.%文章介绍了星载微波光子变频技术的技术类型、特点和应用背景。对比分析了几种典型微波光子变频方案，研究了基于串联铌酸锂调制器的变频器原理，提出了一种星载LN-MZ微波光子变频技术方案，并仿真验证该变频方案的性能，为新型星载微波光子变频方案设计及应用提供了必要的理论依据和技术支撑。
