ATS592411-11

24GHz 1T1R Radar MMIC

The device is an integrated single chip mmWave sensor SoC based on FMCW radar technology. It works at 24GHz K-band with up to 1GHz modulation bandwidth in each single frequency sweeping chirp.

The device includes a fully K-band RF transceiver, driven by on-chip pattern generator and PLL. The pattern generator supports multiple frequency sweeping modes with different time-frequency waveforms, e.g. saw-tooth and triangular waveforms. The pattern generator and PLL support fast chirp mode up to 8kHz chirp rate.

The RF and analog subsystem contain one transmitter (TX) and one receiver (RX). Gain controls are applied to both transmitter and receiver to adjust the whole link budget to work in different scenarios. IQ basebands including inter-mediate frequency (IF) amplifiers, filters and ADCs are integrated for the receivers. A built-in DSP accelerator may process the IQ ADC’s raw data with FFT or Doppler FFT. The processed data can be serialized outputted through SPI or UART interface.

The device requires only a few external components with simple configuration,e.g. the external crystal oscillator and stabilization capacitors due to its high level of integration. Even it can work with a single power supply at 3.3V with the internal power management engine, and the device is fully configurable via I2C/SPI/UART interfaces. The device is an ideal solution for low power, ultra-compact, accurate sensor systems in the AIoT market area.
