  • HBT linearizer and power booster
    Patent number: 6750721
    Abstract: A power amplifier incorporates base ballasted hetero-junction bipolar transistors (HBTs) in parallel. A transistor pair adjusts the voltage applied to the base ballast if it senses that the voltage appearing between one of the HBT transistors and its base ballast is drooping to a level not strong enough to keep the HBTs active.
