An integrated power amplifier includes a divider and a combiner. The integrated power amplifier also includes two or more amplifiers. Each of the amplifier input terminals is electrically coupled to a divider output terminal and each of the amplifier output terminals is electrically coupled to a combiner input terminal. At least one power sensor is configured to provide a power amplifier performance metric. The divider and the combiner include a plurality of actuators. Each actuator has at least one actuator control terminal which is configured to provide an actuator setting. The actuators are configured via the actuator control terminals to optimize the power amplifier performance metric. Methods to simulate the operation of a self-healing power amplifier and a process for the operation of a self-healing circuit are also described.
