MICROWAVE DIPLEXER Russian patent published in 2019 - IPC H01P1/213 

FIELD: physics.

SUBSTANCE: invention relates to a super-high frequencies, in particular to diplexers. Microwave diplexer contains a low-pass filter and a high-pass filter of the second order, the inputs of which are connected together. Inductive element of the low-pass filter is made in the form of a short-circuited loop of a symmetrical ribbon two-wire line on a dielectric, which is installed perpendicular to the input asymmetric microstrip line, and the capacitive element is designed as an open loop asymmetric microstrip line. Capacitive element of the high-pass filter is made in the form of an open loop symmetrical ribbon two-wire line on a dielectric, which is installed perpendicular to the input asymmetrical microstrip line, and the inductive element is designed as a short-circuited loop of an asymmetric microstrip line. All open and short-circuited loops have the same length and the same wave resistance.

EFFECT: improving the quality of matching on the input in the upper part of the decimeter and centimeter range.
