一种低磁化电流铁氧体移相器的研究

Research on a Low Magnetic Current Ferrite Phase Shifter

从理论上分析了双线磁化移相器的原理 ,并进行了实验验证。得出了双线磁化移相器比单线移相器有明显的优越性 ,其磁化电流是单线移相器的一半。文中列举了典型双线移相器的性能 ,其磁化峰值电流只需 6～ 7A ,而其他性能没有明显变化。这对于相控阵雷达波控器和激励器长期、可靠、稳定地工作是一很好的措施。

The principle of a twin wire magnetic phase shifter is analyzed in theory and verified by experiment in this paper.It is concluded that the twin wire magnetic phase shifter has a clear advantage over the one wire magnetic phase shifter and that the former′s magnetic current is half of the latter's.The characteristics of a typical twin wire magnetic phase shifter are also described,its peak magnetic current needs only 6～7A and no obvious changes on other performance arise.It is a good way for phased array radar beam detector and exciter to operate permanently、reliably and stably.
