Abstract

PURPOSE:To establish the amplifier excellent in isolation and small in size, by constituting amplifier in synthesis of a plurality of transistors with the waveguide circuit. CONSTITUTION:The electromagnetic waves from the input waveguide 1 pass through the thin waveguides 2 and 2a split, are amplified at the amplifier 4 and 4a, synthesized through the thin waveguides 3 and 3a and picked up from the output side waveguide 5. The amplifiers 4 and 4a consist of the ferrite plate 6, absorbing resistor 7, transistor 8 and magnet 9 to feed magnetic field to the ferrite plate 6 externally, and it has the construction that a type of field displacement type isolator mounts transistors in inside. Thus, the retrogressing waves produced by the reason of in uniformity of performance of the transitor 8 and being a cause for mutual interference, can be absorbed. Since the transistor 8 is placed at the maximum electric field position of forward waves and selected forward, the forward and reverse ratio of isolator can be increased.
