That is, in this case, two or more amplifier circuits operating in the same frequency band are sandwiched in a single cavity 5 with a reflection circuit composed of a waveguide opening 30 and a short-circuited dielectric waveguide 40 interposed therebetween. By arranging them separately, it is possible to easily secure isolation between the amplifier circuits in which spatial feedback is a problem due to cascade connection, and anti-oscillation can be expected.
