微波环行器、隔离器在雷达固态发射机中的应用

Applications of microwave circulator and isolator in solid state transmitter for radars

微波环行器、隔离器在雷达固态发射机中得到了大量应用,其性能优劣是影响装备性能的重要因素之一,至今仍具有无可取代的地位。简要介绍了该类型器件的基本概念,详细分析了其在雷达固态发射机中的作用,阐述了现代雷达固态发射机对微波环行器、隔离器的迫切需求,结合目前该类型器件存在的技术瓶颈,指出了发展趋势。

Microwave circulators and isolators have been used in solid state transmitter on a large scale, and their performance is one of important factors that affect the performance of equipment. So till now they can not be substituted. The basic concept of this type of devices is briefly introduced. Their function in solid state transmitter of radar is analyzed in detail. In solid state transmitter of modem radar the urgent demand on microwave circulators and isolators is described. The development trend is pointed out combining with the current technology bottleneck of these devices.
