DECIMETER RANGE RECEIVER Russian patent published in 2019 - IPC H04B1/06 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication technology, can be used in reception devices in the decimeter microwave frequency range and is intended to work as part of an active radar system complex as a receiving link for receiving request signals at carrier frequencies. For this, the receiver of the decimeter range includes an identical first receiving channel containing the first amplifier and the mixer, second receiving channel containing the second amplifier and mixer, the third receiving channel containing the third amplifier and mixer, and the fourth receiving channel containing the fourth amplifier and mixer. In this case, the first and third receiving channels are intended for frequency selection, amplification and detection of signals at the first carrier frequency, and the second and fourth receiving channels – at the second carrier frequency. First receiving channel additionally contains the first high-pass filter, thermo-attenuator and the intermediate frequency path, the second receiving channel additionally contains the second high-pass filter, thermo-attenuator and the intermediate frequency path, third receiving channel additionally contains a third high-pass filter, a thermo-attenuator and an intermediate frequency path, the fourth receiving channel additionally contains a fourth high-pass filter, a heat-attenuator and an intermediate frequency path.

EFFECT: technical result consists in creating a receiver of the decimeter range with a single frequency conversion, with functions of the built-in monitoring of the performance of the receiving channels and calibration of their amplitude characteristics, ensuring the processing of signals received at three different carrier frequencies.
