Application note:
The IWR6x43 device is an integrated single chip mmWave sensor based on FMCW radar technology capable of operation in the 60GHz to 64GHz band. It is built with TI’s low power 45nm RFCMOS process and enables unprecedented levels of integration in an extremely small form factor. This device is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the industrial space. Multiple variants are currently available including Functional Safety-Compliant devices and non-functional safety devices.
- FMCW transceiver
- Integrated PLL, transmitter, receiver, Baseband, and ADC
- 60 to 64GHz coverage with 4GHz continuous bandwidth
- Four receive channels
- Three transmit channels
- Supports 6-bit phase shifter for TX Beam forming
- Ultra-accurate chirp engine based on fractional-N PLL
- TX power: 12dBm
- RX noise figure:
- 12dB
- Phase noise at 1MHz:
- –93dBc/Hz
- Built-in calibration and self-test
- Arm Cortex-R4F-based radio control system
- Built-in firmware (ROM)
- Self-calibrating system across process and temperature
- Embedded self-monitoring with no host processor involvement on Functional Safety-Compliant devices
- C674x DSP for advanced signal processing (IWR6843 only)
- Hardware accelerator for FFT, filtering, and CFAR processing
- Memory compression
- Arm-R4F microcontroller for object detection, and interface control
