  • Abstract
    The performance of a three-stage GaAs MESFET amplifier operating in the 11.7 to 12.2 GHz U.S. satellite communication band is characterized between 40°K and 300°K. At room temperature, the noise figure is 5.3 dB (Te=700°K) and the gain is 18 dB. By cooling to 40°K, the noise figure decreases to 1.6 dB (Te=130°K) while the gain increases to 31 dB.
