STRADA770M76-81 GHz transceiver for automotive radar applications

Single-chip RF transceiver with MIPI D-PHY/CSI-2 digital output interface for ADAS radar applications

• ISO26262 ASIL-B support

• AEC-Q100 Grade 2 qualified

KEY APPLICATIONS• ACC (Adaptive Cruise Control)

• AEB (Autonomous Emergency Braking)

• BSD (Blind Spot Detection)

• CTA (Cross Traffic Alert)

Millimeter-wavelength RF sensors are key elements in crash avoidance systems, helping to dramatically improve driving safety when incorporated in advanced driving assistance systems. They are essential components in the fully autonomous self-driving car. Adaptive Cruise Control, Emergency Braking System, Blind Spot Detection are only a few of the applications where the STRADA770M MMIC transceiver can be used. The integration of a 3-channel transmitter together with a 4-channel receiver and a FMCW modulator, significantly reduces the integration effort and guarantees high performance in both short and long-range radar applications.
