Abstract: A system for power amplifier control includes a processor, a memory in communication with the processor, wherein the processor and the memory are configured to simultaneously provide input signal strength of each of a plurality of power amplifiers in a millimeter wave (mmW) phased array system, determine an average input signal strength of the plurality of power amplifiers based on the provided input signal strengths using an analog-to-digital converter (ADC), determine a voltage headroom for the plurality of power amplifiers based on the determined average input signal strength, estimate a power backoff value based on the voltage headroom, and determine a gain control value based on the estimated power backoff value.
