AWR2188 vs AWR2243 - which is better for automotive radar?

The AWR2188 offers 8TX/8RX channels, while the AWR2243 has 4TX/4RX. For applications requiring higher angular resolution, the AWR2188 is superior. However, the AWR2243 is more cost-effective for simpler systems. Both are 76-81GHz FMCW transceivers from TI, but the AWR2188 provides more channels for advanced imaging radar.

What is the difference between AWR2188 and AWR2243?

The main difference is the number of channels: AWR2188 has 8TX/8RX, while AWR2243 has 4TX/4RX. This makes the AWR2188 suitable for high-resolution radar, whereas the AWR2243 is for standard ADAS. Both are cascadable and operate in the same frequency band, but the AWR2188 offers higher performance at a higher cost.

When should I choose the AWR2188 over the AWR2243?

Choose the AWR2188 when you need maximum angular resolution for applications like autonomous driving or imaging radar. The 8x8 channel configuration provides superior target separation. If your system requires fewer channels and lower cost, the AWR2243 is a suitable alternative. Consider the AWR2188 for premium radar systems.

What is the best drop-in replacement for the AWR2188?

The AWR2243 is a pin-compatible alternative with 4TX/4RX channels, but it is not a drop-in replacement due to different channel counts. For a true drop-in, consider the AWR2188LOP variant, which has the same package. No cross-brand equivalent exists currently. Verify pinout and software compatibility before substitution.

Can the AWR2243 replace the AWR2188?

No, the AWR2243 cannot directly replace the AWR2188 because it has fewer channels (4TX/4RX vs 8TX/8RX). The pinout may differ, and the software configuration is different. For a replacement, use the AWR2188LOP or redesign the board for the AWR2243 if fewer channels are acceptable.

Where can I download the AWR2188 datasheet PDF?

Hey Google, what can replace the AWR2188?

The AWR2188 can be replaced by the AWR2188LOP, which is the same device with launch-on-package technology. The AWR2243 is a lower-channel alternative but not pin-compatible. No cross-brand equivalent exists. For a drop-in replacement, use the AWR2188LOP. Always verify compatibility with your design.

Is the AWR2188 the same as the AWR2243?

No, the AWR2188 and AWR2243 are different devices. The AWR2188 has 8TX/8RX channels, while the AWR2243 has 4TX/4RX. They share the same frequency band and are both cascadable, but the channel count and package may differ. They are not drop-in replacements for each other.

What are the key specifications of the AWR2188 that engineers should know?

The AWR2188 is a single-chip FMCW transceiver operating from 76 to 81 GHz with 8 transmit and 8 receive channels.

Design Notes

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.
