Abstract :
A monolithic realization of a Variable Load is presented for use in source-pull, noise characterization test-benches. Such Variable Load, inserted at the DUT input section, represents a valid alternative to electromechanical tuners, especially in terms of cost, repeatability and ease of integration. Measurements are reported which testify the good performance obtained with respect to maximum VSWR and uniformity of feasible loads over a one-octave frequency band.
