HIGHLY SELECTIVE MULTICHANNEL RADIO RECEIVING DEVICE BASED ON BAND-PASS AND TUNABLE BARRIER FILTERS Russian patent published in 2021 - IPC H04B1/18 

FIELD: physics.

SUBSTANCE: invention relates to radio engineering and can be used in equipment of broadband systems of multi-channel communication of KB-range of frequencies. Highly selective multichannel radio receiving device based on band-pass and tunable barrier filters comprises an antilocal filter, protection device, a device for selection, amplification and conversion of signals, a device for selection, amplification and conversion of signals additionally includes a power splitter, one measuring and N information reception channels, unit for digital signal processing, measurement receiving circuit consists of band-pass filter and controlled attenuator, each information reception channel consists of band-pass filter, adjustable guard filter, controlled attenuator and amplitude amplifier. Outputs of measuring and information channels are connected to M inputs of digital signal processing unit, control inputs of attenuators and barrier filters are connected to output of control unit, input of control unit is connected to first output of digital signal processing unit, second output of digital signal processing unit is output of device.

EFFECT: technical result is higher level of blocking.
