SHF POWER DIVIDER-SUMMER Russian patent published in 1998 - IPC

FIELD: division or summation of SHF powers. SUBSTANCE: SHF divider-summer has N cyclically symmetric and one axial coaxial inputs. Coupling region of coaxials is manufactured in the form of screened multiwire transmission line having length $$$ which internal conductors are used as continuation of internal conductors of coaxial transmission line. Ring coupling region of multiwire line with axial coaxial overlaps projection of ring coupling regions with other coaxials if following ratios are realized $$$, $$$, where m= N if N is odd number and m=N/2 if N is even number; D is diameter of screening conductor of length of screened multiwire line; $$$ is diameter of axial conductor of length of screened multiwire line; $$$ is wave length. Condition of beyond cutoff of all types of higher waves ( single-mode operation of device ) is recorded in this form $$$. EFFECT: sufficiently diminished dimensions of device.
