  • Abstract
    The pump modulation factors m of various GaAs and Si varactor diodes have been measured under operating conditions. The device used for the measurements was a phase sensitive degenerate parametric amplifier with a signal frequency of 5.85 Gc phase locked with a pump frequency at 11.7 Gc. The input impedance of the amplifier varies with relative phase of pumped elastance ( \\theta p ) and signal current ( \\theta s ) according to ZV= RS+ frac{S_{o}}{J\\omega _{s}} + {mS_{o}}{\\omega _{S}}e^{J(\\theta_{P}-2\\theta_{S})} The locus of the impedance is a circle which can be plotted directly on a Smith chart. The radius of this circle yields the modulation factor.
