AN EXPERIMENTAL STUDY OF THE PARALLEL PUMPED FERROMAGNETIC AMPLIFIER

Abstract

The performance characteristics of the parallel pumped magnetostatic amplifier are experimentally determined. The gain bandwidth product and noise figure are measured as a function of pump power and compared with the usual parametric amplifier theory. Deviations occur which originate from a broadening of the signal and idle magnetostatic modes. This linewidth broadening increases with pump power and is due to pump saturation effects. When the usual theory for the gain bandwidth and noise figure is corrected, close agreement is obtained with the experimental data.
