Analytical modeling of transducer gain and gain compression in degenerate parametric amplifiers

Analytical models accurately describing transducer gain and gain compression of degenerate parametric amplifiers are presented. To validate the models, a prototype broadband double-balanced phase-coherent degenerate parametric amplifier was constructed that provides an average gain of 26 dB over 1 GHz of usable bandwidth centered at 650 MHz. The analytical models agree with measured data over a wide range of operating conditions.
