An active antenna is disclosed including a passive portion of an antenna array extended at one end by a plate in which apertures are formed, at least one active assembly for transmitting radiofrequency RF waves, called assembly, through said apertures, each assembly including a first row of active modules facing apertures of the plate, a second row of active modules facing apertures of the plate and attached to the first row of active modules, a beam attached to the plate and held clamped between the first and second rows of active modules, a heat-transfer duct in contact with the first and second rows of active modules and jutting out on either side of said first and second rows of active modules.

Active antenna especially for the space-technology field

An amplifier arrangement has a plurality of function strings, which are required for nominal operation. In addition, the amplifier arrangement has a redundancy circuit and a redundant function string including a redundant converter and a redundant amplifier. If a function string is faulty, the redundancy circuit supplies the input signals of the faulty function string to the redundant function string. In addition, a high-frequency system with an inner housing and an outer housing is described, wherein an air gap separates the inner housing and the outer housing from one another so that high-frequency signals can be transmitted via the air gap between the inner housing and the outer housing.
