DIGITAL TRANSCEIVER MODULE OF AN ACTIVE PHASED ANTENNA ARRAY Russian patent published in 2022 - IPC H01Q21/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment, namely, to active phased antenna arrays (APAA) with digital formation and control of the antenna pattern (AP). The technical result is achieved by the the digital transceiver module (PPM) of the APAA of a pulse radar, including the transmitting and receiving channels, as well as, common to both channels, an antenna switch with an emitter, a block of digital bandpass filters, and a block for the formation of digital weighting coefficients, the input whereof is connected to the output of the maximum APAA emission sensor included in the AP formation processor, wherein the transmitting channel includes, connected in series, a DAC and a power amplifier, the output whereof is connected to the input of the antenna switch, and the receiving channel includes, connected in series, a protection apparatus, a low-noise amplifier (LNA), and an ADC.

EFFECT: ensured matched formation of the AP of APAAs in the modes of emission and reception of broadband linear-frequency-modulated (LFM) signals.
