Abstract

The invention relates to the technical field of signal timing, in particular to a device for abnormal power timing and a control method thereof. , down-conversion processing unit, intermediate frequency amplifier to intermediate frequency signal output, wherein, the reference unit and the power switch are respectively electrically connected to the down-conversion processing unit, and the reset module is electrically connected to the power switch. The invention effectively solves the problem that the down-conversion processing unit loses lock due to the external power supply sequence in the radio frequency module.

Description

technical field [0001] The present invention relates to the technical field of signal timing, and in particular, to a device for abnormal power timing sequence and a control method thereof. Background technique [0002] At present, the principle of the radio frequency module used in the receiver is that the radio frequency input signal passes through the power divider, amplifier, filter, down-conversion processing unit, and intermediate frequency amplifier in turn to output the intermediate frequency signal, and the down-conversion processing unit has power input and power input respectively. The unit enters the down-conversion processing unit. In the practical application of the above technology, when the external power supply sequence is complex or uncertain, the external power supply is frequently powered on or the power supply is stepped, and the down-conversion processing unit will lose lock, resulting in abnormal RF output in the entire RF module, and the receiver cann...
