Abstract
An apparatus, comprising has an array of power amplifiers. A power detector collects a power signal applied to the array of power amplifiers. Digital logic is connected to the array of power amplifiers and the power detector. The digital logic is configured to evaluate the power signal and select an array pattern from a set of array patterns and generate a control signal to implement the array pattern on the array of power amplifiers. Each array pattern in the set of array patterns includes at least one operative power amplifier.
