Low Noise, 94 GHz Parametric Amplifier Development

This paper describes the development of a 94 GHz non-degenerate parametric amplfiler, the first of its kind. Included in this discussion is a description of the evolution of the state-of-the-art high-quality varactor, circulator and millimeter-wave circuit technology necessary for low noise 94 GHz paramp realization. Finally, a description of the physical embodiment of the overall 94 GHz paramp is presented aIong with relevant measured performance data.
