摘　　要：旋转场移相器具有移相精度高(均方根误差可小于1°)和温度稳定性好等特点,通过改进射频传输结构,可大大提高他的功率容量。利用旋转场移相器的互易特性和铁氧体圆极化器的非互易特性,设计出高功率双工旋转场移相器。其双工特性可将收/发信号分开,实现移相器和环行器的双重功能,用于天线的收发通道等场合时,可省去一个高功率环行器,结构紧凑。分析了双工旋转场移相器的工作原理,阐述了高功率应用下的设计方法,推导出了管状铁氧体的相移量计算公式,按此方法设计了实用的器件,并给出了试验数据。The rotary field phase shifter has advantages such as high precision of phase shifting (RMS tolerance can be less than 1°) and stable performances in varied temperature. By optimizing the RF transmit structure, its power capability can be increased greatly. Taking advantage of the reciprocity of rotary field phase shifters and nonreciprocity of ferrite circle polarizers, high power duplexing rotary field phase phase shifters are designed. The shifter's duplexing can split the T/R signals and realize he function of phase shifters and circulators. In the case of principle of the duplexing rotary field phase shifter is introduced. The main design method used in a high power condition is also expounded. The formula of phase shift for ferrite pipe is developed. And a practical shifter is produced in the concerned way. The involved test data are also offered. [
