Abstract A section of microwave transmission line is made in the form of three contiguous, in-line, synchronously-tuned, resonant cavities. The end of each cavity is terminated by a symmetrical inductive iris and the spacing between irises is approximately a half wavelgnth at the center frequency of the selected passband. In each cavity there are supported alternate rods of ferrite and nonmagnetic dielectric material all of the same dimensions and of substantially the same dielectric constant. An adjustable magnetic field is provided for the ferrite. The limiting threshold is greatly lowered because of the combined effects of increased RF magnetic field intensity in the cavities compared to that in the transmission line and the nonmagnetic separator rods that direct more of the magnetic flux through the ferrite.
