Patent ID: 8755759

Claim:
A communications device, comprising: a signal generator configured to provide a signal-of-interest to be amplified via a power amplifier and transmitted over an RF antenna; a transmission path extending between the signal generator and the power amplifier and comprising a delay element, wherein the delay element delays the signal-of-interest to provide a delayed signal-of-interest on the transmission path; a control path extending between the signal generator and the power amplifier and comprising a signal analyzer and a tunable DC power supply, wherein the signal analyzer is configured to analyze the signal-of-interest by evaluating an envelope thereof and induce a change in a DC power level provided by the tunable DC power supply based thereon; and wherein the power amplifier receives the DC power level from the tunable DC power supply and amplifies the delayed-signal-of-interest as a function of the DC power level, thereby facilitating transmission of the signal-of-interest over the RF antenna.
