A Nondegenerate Millimeter Wave Parametric Amplifier with a Solid-State Pump Source

Abstract
A state-of-the-art nondegenerate millimeter wave parametric amplifier that utilized a reliable solid-state pump source at 105 GHz has been successfully developed and tested in the 55 to 65 GHz frequency band. A gain of 14 dB with a 1 -dB bandwidth of 670 MHz has been obtained. The measured single-sideband noise factor of the paramp averaged 5.9 dB across the operating passband.
