ABSTRACT:
A lumped constant type ultra-high speed variable delay line includes an inductance element consisting of a single layer solenoid formed by winding a conductor with a prescribed pitch, a capacitor connected between said conductor and ground at each turn, a fixed contact array consisting of fixed contacts respectively formed on said each conductor at each turn of said inductance element, and a movable contact element for sliding on said fixed contact array while alternately making single-contact with one of said fixed contacts and multi-contact with adjacent fixed contacts.
