Abstract
Power limiting circuitry for use with a power amplifier, the power amplifier having (a) a power supply voltage source connected thereto and (b) a load impedance, the power limiting circuitry comprising detecting means for detecting the magnitude of the load impedance; and control means responsive to the detecting means for controlling the magnitude of the power supply voltage applied to the power amplifier; means for sensing the temperature at a predetermined point in the power amplifier and generating an output signal when the temperature exceeds a predetermined amount; and AND circuit means responsive to the detecting means and the temperature sensing means for actuating the control means in response thereto.
