ABSTRACT:
A high-frequency amplifier device according to this invention comprises a high-frequency amplifier portion, a high-frequency input portion which is formed of a waveguide and which can transmit polarized signals orthogonal to each other, two detector portions which are inserted in the waveguide of the input portion and which respectively and independently detect the polarized wave signals orthogonal to each other, an irreversible circuit to which the polarized wave signals detected by the detector portions are individually input and which selectively and switching delivers one of the polarized wave signals to the high-frequency amplifier portion and returns the other polarized wave signal to the input portion, and a switching control mechanism for switching and controlling transmitting directions of the irreversible circuit in response to a control signal externally applied.
