BGT24ATR22E6433XUMA1

BGT24ATR22E6433XUMA1 is a monolithic microwave integrated circuit (MMIC) for 24GHz radar applications. It provides building blocks for analog signal generation and reception, operating in the frequency range from 24GHz up to 24.25GHz. This device features 2 transmit channels, 2 receive channels, a fundamental voltage-controlled oscillator (VCO), an integrated analog baseband (ABB) with offset compensation for intermediate frequency (IF) signal conditioning, and a 12-bit analog-to-digital converter (ADC). A digital finite state machine (FSM) guarantees power-efficient control of the individual submodules including ultra-low power modes. Furthermore, the radar transceiver has integrated radar data preprocessing. Applications include automotive short-range radar, hands-free trunk and door opening, motion detection, and touchless switches.
