AWR2188 概要
A radar transceiver is a device that both transmits and receives radio frequency signals to detect objects and measure their distance, velocity, and angle. In automotive radar, FMCW (Frequency-Modulated Continuous Wave) transceivers are essential for advanced driver-assistance systems (ADAS) and autonomous driving, as they provide robust object detection in all weather conditions. The AWR2188 sits at the top of the radar signal chain, converting RF signals to digital data for processing by a host MCU or DSP.
Key features include 8TX/8RX channels for high angular resolution, cascadable architecture for multiple-device synchronization, and LoP technology that eliminates the need for external antenna packaging, reducing system cost and size. The device supports a wide frequency range of 76-81GHz, enabling both long-range and short-range radar applications. It also includes built-in self-monitoring and calibration features for reliable operation.
Technically, the AWR2188 integrates a fractional-N PLL, multiple ADC channels, and a digital signal processing chain. The cascadable interface allows multiple devices to be synchronized for a larger virtual antenna array, improving angular resolution. The LoP package integrates the antenna on the package itself, simplifying PCB design and reducing signal losses. The device operates from a 1.8V core supply and includes multiple power management features.
Typical applications include automotive radar for adaptive cruise control, autonomous emergency braking, and blind-spot detection. It is also used in industrial radar for level sensing and motion detection. The high integration and small form factor make it ideal for space-constrained designs.
When designing with the AWR2188, ensure proper power supply decoupling and thermal management, as the device dissipates significant power during operation. The cascadable interface requires careful clock synchronization for multi-device systems.

設計ノート
The AWR2188 requires a clean 1.8V core supply. Use low-ESR ceramic capacitors close to the power pins. A dedicated LDO or switching regulator with low ripple is recommended. Ensure adequate decoupling for the RF sections to avoid noise coupling.
The AWR2188 dissipates significant power during operation. Provide a thermal pad connected to a large copper area on the PCB. Consider a heatsink or forced airflow for high-duty-cycle applications. Monitor junction temperature to prevent overheating.
For the RF channels, use controlled impedance traces and keep them short. The LoP package integrates antennas, so no external antenna design is needed. Ensure proper grounding and via stitching around the RF area. Follow TI's layout guidelines in the datasheet.
