Abstract
A source of millimeter waves adjustable in power and frequency and embodied as a cylindrical waveguide one end of which is provided with a movable piston and the other end with a directive antenna generally a radiating horn. Between the ends is tapped a cylindrical waveguide branch in which slides a sub-assembly carrying a radiating module containing an oscillating diode. The position of the module affects the power and the frequency of oscillation of the source and the position of the movable piston acts on the power emitted by the radiating horn.
