FREQUENCY-DOMAIN DECOUPLER Russian patent published in 2014 - IPC H01P1/00 H01P1/213 

FIELD: radio engineering, communication.

SUBSTANCE: frequency-domain decoupler for connecting multiple sources or loads operating at different frequencies, with a common load or source, is made using a microstrip technology on a printed-circuit board in form of a microstrip structure which includes two open rings, each having two tuning arms and two matched inputs, one of which is common for the two open rings. Each tuning arm ends with tuning elements. The frequency-domain decoupler is adapted to simultaneously use, as a frequency adder, two signal sources operating in different frequency ranges, and a common source, as well as a frequency divider for dividing the signal of the common signal source into two signals with different frequency ranges.

EFFECT: broader functional capabilities, improved decoupling of sources, minimising useful signal loss and high stability of parameters under climatic effect.
