This paper presents a discovery that Metaphysics Electricity Bridge（MEB） Principle（MEBP） can be applied to the auto gain control（AGC） of the radio frequency（RF） channels,including active and passive circuits.In this paper,the basic theory of MEBP AGC is discussed,which consists of the transfer function,AGC transfer voltage,the limit gain precision of the MEBP AGC model,and the MEB balance model（MEBM）.Further,the design of the MEBP AGC is provided,and the corresponding principle,AGC transfer voltage formed,is also delivered.Finally,the effectiveness of the MEBP AGC was demonstrated through S band RF channel,and the output power curve was plotted out of the temperature experiment data.The result indicates that the gain error of MEBP AGC is less than 0.2 dB.
