Abstract
In a method of fabrication of a module formed by a semiconductor diode which oscillates in millimeter waves and by a variable-capacitance diode, the oscillating diode is mounted on a pedestal at the center of a support base. A ring of fused silica for supporting a metallic disk of predetermined diameter serves to form a radial space between two metallic surfaces with a view to readily obtaining oscillation in a predetermined frequency band. A similar ring is welded at one end to the opposite face of the disk and at the other end to another metallic base fitted with a central variable-capacitance diode. Flexible connections bonded to the diodes are clamped between the rings and the disk. The module may be incorporated in a tunable oscillator.
