The utility model relates to microwave frequency technology. A hybrid ring bridge is presented as a ring with length equal to wave length of operating range middle divided by transmission lines, which are connected to the bridge, into four equal bridge branches. Two branches are presented as sections of transmission lines, the third – band filter with transmission lines section at edges. The fourth branch consists of three sections of transmission lines: a central one being short-circuited at ends, and two end sections. Length of the central section and loops length are equal to the length of the band filter. End sections are made the same length and having the same wave resistance as section at ends of the band filter. To improve matching from transmission line side, between the transmission line, which divides bridge shoulders and connection portion of the third and the fourth shoulders it is in series connected an open loop.: |
