Abstract

The invention discloses a walkie-talkie voltage regulator module facilitating voltage discharge. The walkie-talkie voltage regulator module comprises a resistor I, a resistor II, and an N-channel enhancement type insulated gate field effect transistor I, wherein two ends of the resistor I are connected with the resistor II and a drain of the N-channel enhancement type insulated gate field effect transistor I respectively, a source of the N-channel enhancement type insulated gate field effect transistor I is grounded, the other end, opposite to the end connected with the resistor I, of the resistor II is connected with a gate of the N-channel enhancement type insulated gate field effect transistor I, a direct current voltage input line is connected on a line between the drain of the N-channel enhancement type insulated gate field effect transistor I and the resistor I, and a direct current voltage output line is connected on a line between the resistor II and the resistor I. Through adoption of the above structure, the whole walkie-talkie voltage regulator module has a simple structure, is easy to realize, and prevents a discharged voltage from jumping due to action of the N-channelenhancement type insulated gate field effect transistor I when in use, so as to avoid demodulation failure.

There is a voltage stabilizing circuit in the walkie-talkie. The voltage stabilizing circuit is mainly used to prevent the rectified DC power supply voltage from being too high, and to discharge the excessively high DC voltage. The existing voltage stabilizing circuit is to adjust the power supply voltage and a certain standard voltage Then, the voltage to be discharged can be obtained. The discharge voltage obtained in this way will have a process of sudden voltage jump, which will cause a large change in the discharge current before and after the jump. This may make the modulation depth of the received signal in The field strength in a certain range is very small, which will lead to demodulation failure
