首先,阐述了一种铁氧体移相器控制系统,包含波控与移相器驱动电路两部分;然后,由项目设计角度出发,详细介绍了基于FPGA的波控电路设计方法,以及移相器位数与单位脉宽的关系;最后,阐明了移相器工作原理和移相器驱动电路的构成。

First of all. A control system for ferrite phase shifter is described, which contains beam-steering and phase shifter driver circuit. Then from the viewpoint of project design, a design method of beam-steering circuit based on FPGA and the relationship between bits of the phase shifter and unit pulse wide are introduced in detail. And finally the work principle of phase shifter and the components of phase shifter driver circuit are demonstrated.
