Method and device for controlling power supplying voltage of power consumption device in emitting passage and emitting system

Abstract

The embodiment of the invention provides a method and device for controlling power supplying voltage of a power consumption device in an emitting passage and an emitting system, relating to the technical field of communication and solving the technical problem that the power consumption of an emitting passage in the prior art is higher. The method for controlling power supplying voltage of the power consumption device in the emitting passage comprises the steps of: sensing the amplitude of the I / O signals to be emitted or sensing the amplitude of the radio frequency signals which are obtained by carrying out digital-to-analog conversion on the I / O signals; and boosting the voltage output to a grid of a radio frequency power amplifier for amplifying the radio frequency signal power when the amplitude is enlarged and reducing the voltage which is output to the radio frequency power amplifier when the amplitude is reduced. The device for controlling the power supplying voltage of the power consumption device in the emitting passage comprises a sensing module and a controlling module. The emitting system comprises the emitting passage and the device for controlling the power supplying voltage of the power consumption device in the emitting passage, disclosed by the invention. The method and device disclosed by the invention are used for reducing power consumption brought about by the emitting passage part of the complete unit.
