摘要
提出了中频移相器的一种设计方法 ,分析了移相器的工作原理 ,推导了移相器的幅相特性 ,并将其应用于毫米波雷达正交解调器的信号变换中 ,实现了对输入信号相位在 0°～ 1 80°之间的连续调节。
The designing method of MF phaser was discussed in this paper, the principle of device was introduced. The amplitude-phase characteristic of phaser was derived, and it was used in mmW radar I and Q demodulation.The 0°～180° modulation was finished by the device.
