Abstract
An adaptable DC power consumption circuit is provided, wherein the voltage supplied to an RF amplifier is dynamically varied from a desired level. A feedback control loop is formed between the power terminal and a control terminal of a variable voltage supply. A controller influences the feedback control loop to properly set the supply voltage at the desired minimum level necessary to maintain linear operation of the RF amplifier. The output of the RF amplifier influences the feedback control loop to dynamically vary the supply voltage from the desired level. In this manner, linear operation of the RF amplifier can be maintained while maximizing the power efficiency of the RF amplifier.
