DIRECTIONAL BRIDGE Russian patent published in 2017 - IPC H01P5/18 

FIELD: electricity.

SUBSTANCE: there are resistors and balancing transformer placed at the printed-wire board. The printed-wire board is made of three layers of microwave dielectric, wherein the upper and lower layers are made from a Rogers RO4350 material, and the middle layer is made of RO4450 material. Topology of the inner and lower layers is a rectangular polygon which is connected to the housing by means of through vias. There is center conductor of coaxial transmission line on the inner layer, which is connected to the microstrip transmission line on the upper layer with a blind vias.

EFFECT: simplification and reduction of the cost of manufacturing the directional bridge, extension of the range of operating frequencies, as well as reduced size and weight.
