Abstract :
A spacecraft 15-GHz parametric amplifier having a 500-MHz 1-dB bandwidth at 18-dB gain and 140 K noise temperature has been demonstrated. The 14-ounce unit incorporates the amplifier mount, 5-port circulators, varactor doubler, Gunn oscillator, and pump source. The maximum dc input of 11 watts includes stabilization over -5 to +50/spl deg/C in a thermal-vacuum environment.
