ABSTRACT:
A tunable delay line for radiofrequency applications includes a waveguide and a dielectric perturbing member that is displaceable relative to the waveguide for varying the delay imparted by the line. The waveguide is a ridge waveguide and the perturbing member is arranged parallel to a longitudinal end surface of the ridge and is movable in the ridge plane, toward and away from the ridge end surface, or in a direction transversal to the ridge.
