  • Low-power feedforward amplifier
    Patent number: 4812779
    Abstract: A feedforward trunk amplifier having the distortion advantages associated with the feedforward topology while providing significantly reduced power consumption and cost. The trunk amplifier has a discrete preamplifier including active gain and slope control, and a low-power feedforward output stage including a medium-gain, hybrid main amplifier, a high-gain, discrete error amplifier having two gain stages which share the same bias current, and miniature coaxial cable delay lines mounted on the cover of the amplifier housing.
    Type: Grant
