Embodiment 1

[0129] like image 3 As shown, the method for controlling the power supply voltage of the power consumption device in the transmission path provided by the embodiment of the present invention includes the following steps:

[0130] S1. Sensing the magnitude of the I / Q signal to be transmitted;

[0131] S2. Increase the voltage output to the grid of the radio frequency power amplifier for amplifying the power of the radio frequency signal when the amplitude increases, and decrease the voltage output to the grid of the radio frequency power amplifier when the amplitude decreases.

[0132] Because in the embodiment of the present invention, the amplitude of the I / Q signal that needs to be transmitted can be sensed first, and then the voltage output to the gate of the RF power amplifier for amplifying the power of the RF signal is increased when the amplitude increases, and decreased when the amplitude decreases. The voltage output to the gate of the radio frequency power amplifie...

Embodiment 2

[0215] like Figure 7 As shown, Embodiment 2 of the method of the present invention is basically the same as Embodiment 1 provided by the present invention above, and the difference is that step S1 in this embodiment is: sensing the amplitude of the radio frequency signal after the digital-to-analog conversion of the I / Q signal size.

[0216] In the same way as Embodiment 1 of the method of the present invention, in the embodiment of the present invention, the amplitude of the radio frequency signal after the digital-to-analog conversion of the I / Q signal can be sensed first, and then output to at least one radio frequency power amplifier (such as the final radio frequency power amplifier) ​​according to the amplitude in real time. level RF power amplifier) ​​grid voltage, it can be seen that step S1 in the second embodiment of the method of the present invention and step S1 in the embodiment 1 provided by the present invention are corresponding specific technical features, be...

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.
