Power Amplifier Temperature Feedback for Stable mmWave EIRP

The patent implements a feedback mechanism where the controller continuously monitors the temperature of the power amplifier and adjusts the input power accordingly. When temperature increases causing gain drop, the controller reduces input power to prevent overheating and maintain stable operation, creating a closed-loop control system that resolves the contradiction between maintaining high output power and controlling temperature.

The patent dynamically changes the input power parameter based on temperature conditions. By adjusting the input power level according to real-time temperature measurements, the system adapts its operating parameters to maintain optimal performance across varying thermal conditions, resolving the contradiction between power output and temperature control.

The controller uses feedback from temperature sensors to determine when gain drop occurs and only increases input power when necessary to maintain effective isotropic radiated power. This conditional feedback approach avoids unnecessary power consumption while ensuring EIRP requirements are met only when thermal conditions warrant such compensation.

Instead of continuously operating at maximum power levels, the system applies partial action by adjusting input power only to the extent necessary to compensate for temperature-induced gain drop. This prevents excessive power consumption while maintaining adequate EIRP performance under varying thermal conditions.
