STRIPLINE DEVICE FOR QUADRATURE DIVISION AND SUMMATION OF MICROWAVE SIGNALS Russian patent published in 2015 - IPC H01P5/00 

FIELD: physics, radio.

SUBSTANCE: invention relates to radio engineering and can be used in broadband receiving, transmitting and measurement microwave devices. A stripline device for quadrature division and summation of microwave signals comprises a dielectric board, the back side of which is metal-coated, placed on a metal base, a system of closely arranged electromagnetically coupled stripline conductors and four supply stripline electrodes placed on the front side of the board, wherein a rectangular window is formed in the metal coating on the back side of the board coaxially to the system of coupled stripline conductors, the length of said window being equal to the length of the system of coupled conductors and the width being greater than the total width of the system of coupled stripline conductors, wherein a rectangular cavity is formed in the metal base under the formed window, the depth of said cavity being at least half of the thickness of the dielectric board and the width being more than 5% greater than the width of the window in the metal coating of the dielectric board.

EFFECT: high power of microwave signals and reduced losses.
