Power supply time sequence abnormity device and control method thereof

The invention relates to the technical field of signal time sequence, in particular to a power supply time sequence abnormity device and a control method thereof, an input power supply is electrically connected with a power supply switch, a reset module and a reference unit respectively, and radio frequency signal input passes through a power divider, an amplifier, a filter, a down-conversion processing unit and an intermediate frequency amplifier in sequence to intermediate frequency signal output, the reference unit and the power switch are electrically connected with the down-conversion processing unit, and the reset module is electrically connected with the power switch. According to the invention, the problem that the down-conversion processing unit loses lock due to the time sequence of the external power supply in the radio frequency module is effectively solved. 本发明涉及信号时序技术领域，尤其涉及一种用于电源时序异常装置及其控制方法，输入电源分别电连接电源开关、复位模块和参考单元，射频信号输入依次通过功分器、放大器、滤波器、下变频处理单元、中频放大器至中频信号输出，其中，参考单元和电源开关分别电连接下变频处理单元，复位模块电连接电源开关。
