1. An arrangement for high-power amplifying a signal, the arrangement comprising:
- an antenna arrangement including;
an antenna feed arrangement comprising a predetermined aperture and capable of transmitting or receiving a signal; and
a main reflector comprising a predetermined aperture capable of bidirectionally reflecting a signal between the predetermined aperture of the antenna feed arrangement and the predetermined aperture of the main reflector; and
an amplifier array disposed at the predetermined aperture of the main reflector with at least a predetermined axis of said array disposed at an image surface of the aperture of the antenna feed arrangement, the array covering substantially the entire image of the aperture of the feed arrangement, the amplifier array comprising;
a plurality of parallel mounted corresponding waveguide sections, each waveguide section of the array including (a) a solid state amplifier arrangement, (b) a first waveguide subsection for directing a signal received at an aperture thereof to an input of the solid state amplifier arrangement, and (c) a second waveguide subsection for directing an amplified signal at the output of the solid state amplifier arrangement to an aperture of the second waveguide subsection for transmission from the amplifier array, each of the first and second waveguide subsections including means for providing an impedance match between the aperture thereof and the solid state amplifier arrangement.

Abstract
The present invention relates to a high-power solid state amplifier arrangement comprising a large number of solid state amplifiers disposed in a waveguide array. The waveguide array is disposed in the aperture of an antenna feed arrangement at the image plane of an antenna feed to receive a uniform distribution over the array with substantially no spillover. Each of the large number of parallel waveguide sections of the array includes one or more solid state amplifiers in a serial, waveguide-interconnected, arrangement, and a wideband impedance matching arrangement in the waveguide configuration at the input and output of the section.
