Automotive Radar Modules From China
2 resources tagged with "Radar"
Radar sourcing from China centers on 76–81 GHz FMCW modules for ADAS, typically built on TI AWR-series or NXP TEF810X transceivers paired with an S32R companion MCU. The non-negotiable for automotive radar is AEC-Q100 grade on the RF and processing silicon — a module using consumer-grade or unverified-grade parts has no place in a vehicle program. On the regulatory side, 77 GHz operation must clear FCC (US) and ETSI (EU) limits, and Chinese OEMs vary widely in whether their modules already hold that compliance.
When you source radar modules, verify the chipset's AEC-Q100 grade and the module's FCC/ETSI compliance before anything else — these are the gates for a road-legal automotive part. We check the transceiver/MCU pairing, grade documentation, and RF test reports rather than trusting a spec sheet headline.

FAQ
What frequency do automotive radar modules use?
Modern ADAS radar uses the 76–81 GHz band with FMCW modulation. The 77 GHz long-range and 79 GHz short-range allocations are the global automotive standard, replacing older 24 GHz designs.
What grade must the radar chipset meet for automotive use?
AEC-Q100 qualification is mandatory for the RF transceiver and processing MCU in any vehicle program. Confirm the grade (and temperature grade) in the part documentation, because non-automotive-grade silicon will not pass OEM qualification.
Do Chinese radar modules come FCC/ETSI compliant?
Some do, many don't. 77 GHz operation must meet FCC limits in the US and ETSI limits in the EU; request the module's existing RF compliance reports rather than assuming the band is approved for your market.
