Abstract:
Methods and systems for modulating an amplifier power supply to efficiently attain amplified RF output power with much lower power dissipation than existing amplifiers. In a cable television (CATV) network, a processor receives a signal to be amplified by an amplifier at a location remote from the processor. A bias point of the amplifier may be variably modulated based on peaks of an input signal to reduce amplifier dissipation.

Claim (Index 24):
A device having an amplifier operable for amplifying an input signal, the device reducing power dissipation by modulating an amplifier voltage source, the device comprising:\n a first amplifier voltage source, wherein an amplifier amplifies signals with power provided via an output from the amplifier voltage source; a second amplifier voltage source producing a waveform representing the input signal to amplify; and an amplifier bias current control circuit driven by a bias signal generated by passing samples of the input signal to amplify through a peak detection circuit, an output from the amplifier bias current control circuit causing variable changes to a bias point of the amplifier to coincide with peaks in the input signal, wherein the bias point of the amplifier modified by the amplifier bias current control circuit output is varied to reduce power consumption of the amplifier; the amplifier driven by a delayed input signal adjusted in response to changes in the envelope signal of the bias signal, wherein the delayed input signal is the input signal delayed by a number of samples for coinciding a response of the bias signal with at least one peak in the input signal; and an output transformer of said amplifier with coupled windings for reducing resistance to common mode current fluctuations cause by the changes to the amplifier bias point.
