Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for adjusting the grid bias voltage of a power amplifier on demand to realize energy saving and consumption reduction. Background technique [0002] The main purpose of the invention is to solve the problem that the power consumption of the power amplifier under fixed bias voltage is relatively large when the voltage-controlled power amplifier is in the class A amplification working mode. At home and abroad, there are many solutions to the problem of high power consumption caused by the low efficiency of class A power amplifiers, such as the use of power amplifiers with amplification modes such as class B and class C. But at present, in domestic wireless communication, especially in mobile communication, due to the simple implementation and convenient development of class A amplification, it is very common for the power amplifier module of repeater station to adopt th...
