2.3.1 AWR6843/1843 Single-Chip Radar Solution

The AWR6843/1843devices are integrated single-chip FMCW sensors capable of operation in the 60-GHz to 64-GHz and 76-GHz to 81-GHz bands. They are built with TI’s low power 45-nm RFCMOS process, and enables unprecedented levels of integration in an extremely small form factor. They are an ideal solution for low power, self-monitored, ultra-accurate radar systems in the automotive and industrial space.

The AWR6843/1843 EVMs have the following features:

• AWR6843 or AWR1843 mmWave radar device.
• Power management circuit to provide all the required supply rails from a single 5-V input.
• Three onboard TX antennas and four RX antennas.
• Onboard XDS110, which provides JTAG interface, UART1 for loading the radar configuration to the device, and UART2 to send the object data back to the PC.
