A simple approach for design of coaxial reflection coefficient standards

Abstract

A simple approach for design of coaxial reflection coefficient standards has been described. Coaxial transfer standards of voltage standing-wave ratios 1.30 and 1.50 have been designed at 4 GHz in the form of a step-up quarter-wave coaxial line terminated by a precision match termination. The uncertainties in the reflection coefficient magnitude of the coaxial standards due to the effect of discontinuity susceptances, dimensional tolerances, and reflection from the match termination have been presented.
