Abstract
The effect of a different value of series resistance associated with the varactor in its imbedding at each of the important frequencies present in a one-port parametric amplifier is analyzed. The modified equations for effective noise temperature, amplifier gain and pump power required thus obtained are compared to experimental values measured on a 4.8 Gc/s parametric amplifier. Finally a simple and precise method for adjusting the amplifier to get close correlation between the measured varactor parameters using Kurokawa´s method at signal idler, and pump frequencies and the overall amplifier performance is presented.
