TANDEM COUPLER ON COUPLED LINES Russian patent published in 2019 - IPC H01P5/18 

FIELD: physics.

SUBSTANCE: invention can be used for directional tapping of part of power from HF and SHF channels. Essence of invention consists in that device for branching HF and SHF part of flux of electromagnetic radiation with given parameters for receiving-transmitting equipment is made of microstrip lines located on two rectangular horizontal dielectric substrates, which reverse side has solid metallization, metal-coated substrate parts are mirror-like interlaced with planes, wherein common-mode component is formed in one arm, and in the other quadrature signal component, on each substrate microstrip lines are applied by photolithography, connection of two microstrip lines with topological cross hair at the connection points is made in the form of straps of foil on the board faces, wherein at one of outputs there is connection of resistor compensating reflection of output signal, at that resistor can be film, suspended or connected by means of SHF connector.

EFFECT: enabling reduction of weight and dimensions of the finished product, high stability of transmission and phase characteristics, high broadband content, reduced effect of the length of the microstrip line on amplitude-frequency characteristics.
