MICROWAVE MIXER Russian patent published in 2013 - IPC H03D7/00 

FIELD: electricity.

SUBSTANCE: microwave mixer comprises a coaxial-waveguide T-bend in the form of a section of a rectangular waveguide, a coaxial line of transfer - output of converted frequency, an insulating substrate, on one side of which there is a metallised coating, and on the other one - an integrated circuit with an active element, a low frequency filter, at the same time the insulating substrate is arranged along the waveguide, in the middle and perpendicular to its wide wall, the insulating substrate is arranged from a semiconductor material of type A^IIIB^v, the metallised coating of the insulating substrate is arranged locally, the non-metallised part of the insulating substrate is arranged in the form of smooth transitions at the opposite ends of the insulating substrate, on the other side of the insulating substrate at both of its opposite sides there are additionally arranged L-shaped metal conductors, and the integrated circuit with an active element, a low frequency filter and L-shaped metal conductors are arranged in the form of a solid integrated circuit, the active element of the solid integrated circuit is made in the form of a field transistor with a Schottky barrier.

EFFECT: expansion of working range of frequencies, including extremely high ones, reduced losses of conversion.
