Abstract :
A broadband double-balanced phase-coherent degenerate parametric amplifier is presented that provides an average gain of 26 dB over 1 GHz of usable bandwidth centered at 650 MHz. A prototype board was constructed, and its measured and simulated data match well with one another. Using a harmonic-balance simulator, the stability of the amplifier was analyzed by observing the evolution of the system poles as both the pump power level and the temperature of operation varied.
