90°正交混合器的AM／PM转换功能及其应用

Quadrature-hybrid used as an AM/PM converter and its applications

用９０°正交混合器做ＡＭ／ＰＭ转换器件，应用在８００ＭｅＶ电子储存环束流位置监测器信号处理电路中获得了理想的效果。

The principle of quadrature-hybrid used as an AM/PM converter is presented.The vector relation between signals at port A, B, C and D is illustrated. Application of this AM/PM converter in the beam position monitor at NSRL is described briefly.
