This electromagnetic variable delay line includes: a delay line, which includes an inductance device and at least one variable capacitance diode connected thereto, and possessing a non linear operational property; and a circuit device for supplying an output control signal to the variable capacitance diode in a manner which varies non linearly with an input control signal. The circuit means has a non linear property which is substantially complementary and opposite to the non linear delay property of the delay line. Optionally but desirably, the delay line may include: several delay line elments, connected in series, each of which includes an inductance device and a variable capacitance diode connected to the inductance device, the variable capacitance diodes being connected together; and buffer circuits connecting together each adjacent pair of these delay line elements.
