77GHz Automotive Radar Modules from China
2 resources tagged with "77ghz"
77GHz (the 76–81 GHz FMCW band) is the automotive radar band for ADAS — adaptive cruise, blind-spot, and collision warning — and Chinese module makers build around TI AWR or NXP TEF810X RFCMOS front ends. Because these go into vehicles, the parts have to be AEC-Q100 qualified, and the finished module needs FCC (US) or ETSI (EU) approval for the 76–81 GHz allocation. The sourcing risk is a module using consumer-grade silicon dressed up as automotive, so verifying the AEC-Q100 grade on the actual transceiver is non-negotiable.
When you source 77GHz radar, the trap is unqualified silicon and missing band certification. We verify the AEC-Q100 grade of the RF transceiver and confirm FCC/ETSI compliance for the destination market before sign-off.

FAQ
Which chipsets power Chinese 77GHz radar modules?
Most use TI AWR-series or NXP TEF810X RFCMOS transceivers, often with a companion MCU like NXP S32R. Confirm the exact part and its AEC-Q100 grade rather than trusting the module's marketing spec.
What certification does a 77GHz radar need?
For the 76–81 GHz band it needs FCC authorization in the US or ETSI compliance in the EU, plus AEC-Q100 on the silicon if it's going into vehicles.
