QuinStar Technology’s QTC series termination is a section of circular waveguide with an integral conical load made from a dielectric absorber material. The long precise taper allows optimum absorption of the microwave energy with minimum reflection. Each termination is fitted with a standard male or female circular flange, specified at the time of order. The QTC terminations are used in experimental and developmental test set-ups where a low VSWR waveguide load is essential for measurement validity. When measuring the VSWR that results from insertion of various waveguide components in a system, these terminations ensure precise determination of the individual effects.
