  • Abstract
    The bandwidth characteristics of two-idler parametric amplifiers are investigated, and an approximate equivalent circuit derived. It is shown that under certain conditions the input impedance Zin is nearly constant and independent of pump amplitude over a relatively wide bandwidth. Computer analysis of particular one- and two-idler amplifiers has yielded comparable bandwidths and noise figures for a single-idler amplifier with a compensating resonator at its input, and a twoidler amplifier. Measured results are given for an experimental two-idler amplifier.
