Abstract:
A high-gain amplifier for amplifying electrical signals distributed in a high-frequency band, the amplifier comprising:a support;an amplification circuit mounted on the support, the amplification circuit comprising an input on a first side and an output on a second side opposite from said first side;a cover disposed over the amplification circuit; andsubdivision means for subdividing into a plurality of auxiliary waveguides a space situated between the cover and the support, the characteristics of the auxiliary waveguides being unsuitable for enabling a signal whose frequency is situated in the high-frequency band of the amplifier to propagate between the output and the input of the amplification circuit, wherein the subdivision means comprises a bar having a conductive outside surface, aligned in a direction going from the input to the output of the amplification circuit, and disposed between the support and the cover, on edges of integrated circuits forming the amplification circuit.
