  • Thermally stable ALC for pulsed output amplifier
    Patent number: 5371473
    Abstract: A method and apparatus incorporating a single self-compensating diode power detector in the feedback loop of a pulsed amplifier for exploiting the discontinuous nature of the pulsed amplifier to extract any thermally induced error voltage by a single power detector between the transmission bursts and use it to correct the power detector voltage during the bursts to obtain a true power indicative voltage, independent of temperature variation.
