MICROWAVE SWITCH-DIVIDER Russian patent published in 2017 - IPC H01P1/00 

FIELD: radio engineering, communication.

SUBSTANCE: microwave switch-divider contains a ring transmission line, to which a input and two output lines are connected at a distance of a quarter wavelength from each other, wherein the wave resistance of the ring line is in the range of Z₀ to √2×Z₀, where Z₀ - the wave resistance of the input and the output lines. The first and the second switching diodes are included in the output lines, at a distance from the connection point to the ring line, less than one eighth of the wavelength, parallel to the ring transmission line. The third switching diode is connected to the middle of the ring line between the connection points of the output lines, to the other end of which a line segment is connected, shorted at the other end, and with a length of less than one eighth of the wavelength.

EFFECT: ensuring good alignment over a wide frequency range in both modes.
