ULTRA-WIDE INSTANTANEOUS RECEPTION BAND Russian patent published in 2024 - IPC H04B7/00 H04L27/22 H04B1/16 

FIELD: radio engineering.

SUBSTANCE: invention can be used in broadband radio receiving devices (RRD) with ultra-wide instantaneous reception band, having limitations on weight and size characteristics and power consumption. Radio receiving device with ultra-wide instantaneous reception band further comprises in-series connected controlled attenuator, low-noise amplifier, in-phase power divider, first and second sampling-storage circuits, first and second low-pass filters and first and second DC amplifiers. Two outputs of phase shifter are connected to gate inputs of sampling-storage circuits, providing an individual phase shift during frequency conversion in each Nyquist zone between signals at the outputs of the two sampling-storage circuits, which allows phase filtering of signals, and the input of the phase shifter is connected to the output of the gate signal generator.

EFFECT: increase in the width of the instantaneous reception band of the radio receiver and minimization of hardware costs due to processing of radio signals with simultaneous transfer to the intermediate frequency band of several sections of the operating frequency range and their separation at the intermediate frequency using phase filtering.
