STRIP HYBRID RING BRIDGE Russian patent published in 1995 - IPC

FIELD: S H F equipment. SUBSTANCE: strip hybrid ring bridge has ring of strip line which total length equals to one and half length of wave and four strip transmission lines connected to it at distance of quarter-wavelength between adjacent lines. Section of ring having length equal to 3/4 length of wave is coupled electromagnetically over entire length to the rest of quarter-wavelength sections. Value of electromagnetic coupling of section of ring with length equal to 3/4 length of wave may not be equal over its length. EFFECT: enhanced operational stability. 2 cl, 3 dwg
