The AWR1843AOP is an integrated, single-chip, FMCW sensor capable of operation in the 76 to 81 GHz band (see Figure 2-2). The sensor is built with the low-power, 45-nm, RFCMOS process from TI and enables unprecedented levels of integration in an extremely small form factor. It integrates a wide FOV antenna-on-package. The AWR1843AOP is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in the automotive and industrial space.

There are several benefits of an antenna-on-package technology:

• Small form factor: Antenna on the PCB takes up almost ~30% of the board space. With the antenna now integrated on the package, the size of the sensor reduces by ~30% compared to conventional sensors. This helps in easy vehicle integration.
• Faster design cycle: Developer need not spend time on simulation and characterization of the antenna parameters.
• Lower PCB cost: Low cost FR4 based PCB can be chosen for design instead of expensive roger’s materialbased PCB.

The AWR1843AOP has the following features:

• AWR1843 radar device
• Antenna on Package with three TX antennae and four RX antennae
• Power management circuit, to provide all the required supply rails from a single 5-V input
• Built-in calibration and self-test (monitoring):
  • ARM Cortex-R4F-based radio control system
  • Built-in firmware (ROM)
  • Self-calibrating system across frequency and temperature
• On-chip memory: 2 MB RAM
