Abstract
Standard graphical procedures for determining varactor cutoff frequency can be replaced by calculations invariant under lossless transformation, applied to measurements at three or four biases at a fixed frequency. Like the graphical method, this numerical formulation minimizes the effect of errors in the measurement of high values of reflection coefficient.
