Abstract : The patent describes a variable direct current (DC) bias control circuit for linear gain operation of a radio frequency (RF) power transistor. A DC amplifier is coupled to sense the change in voltage drop across a biasing resistor of the RF power transistor and is operative to maintain this voltage drop constant to provide a linear gain of the power transistor throughout 10% to 90% of its rated power output within a 1 1/2 decibel variation.
