A straight waveguide distributor (12) distributes inputted power for high-frequency signals to each opening (10). Amplifier boards (15) which are mounted upon a base (2) are provided respectively for the openings (10), disposed in parallel to each other, and connect to the straight waveguide distributor (12). A straight waveguide combiner (13) has openings (11) formed corresponding to the amplifier boards (15), and connects to the amplifier boards (15). A conductive amplifier cover (3): has partitions formed thereon for each of the amplifier boards (15) which isolate the circuits of the amplifier boards (15) continuously from the straight waveguide distributor (12) to the straight waveguide combiner (13); and, except for the openings (10) and the openings (11), covers the entire surfaces of the amplifier boards (15) on the sides nearest the straight waveguide combiner (13). Each of the amplifier boards (15) comprises: a waveguide-microstrip transformer (16) which corresponds to the opening (10); an amplifier element (1); and a microstrip-waveguide transformer (17) which corresponds to the opening (11). |
