MICROWAVE MULTIPLEXER Russian patent published in 2018 - IPC H01P1/213 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering. Microwave multiplexer contains a device for the common leg of the microwave signal, a summing resonator, and parallel-located band-pass filters. Summing resonator is a short-circuited at the ends section of the transmission line, and each of the band-pass filters is made in the form of a chain of coupled resonators. Resonators of each chain of a band-pass filter are located with the formation of two tiers. Separate input devices of microwave signals and the output device of the microwave signal are made in the form of waveguides separated from the corresponding input resonators of chains of band-pass filters and the summing resonator, with transverse diaphragm with coupling slots. Waveguide of each of the separate input devices of microwave signals is equipped with a resonant element in the form of a rod made of dielectric material placed on the transverse diaphragm of the waveguide and with adjusting elements for frequency and coupling tuning, disposed in the waveguide wall. Resonance element is oriented along the propagation direction of microwave signal and is configured to adjust to the boundary frequencies of the multiplexer wide band.

EFFECT: technical results – mass and dimensions reduction, increase in the power level of the output microwave signal.
