CONTINUOUSLY TUNABLE DELAY LINE

摘要

A tunable delay line (1) for radiofrequency applications includes a waveguide (2) and a dielectric perturbing member (4) that is displaceable relative to the waveguide for varying the delay imparted by the line (1 ). The waveguide (2) is a ridge waveguide and said perturbing member is arranged parallel to a longitudinal end surface (3a) of the ridge (3) and is movable in the ridge plane, towards and away from the ridge end surface, or in a direction transversal to the ridge.
