Preliminary Short-form Datasheet
RAA270205
Automotive Radar Transceiver
Description
Radar MMIC is a multi-channel high resolution MIMO RADAR
device targeted for automotive applications.
Operating in the 76 to 81GHz frequency band, the device
supports the highest number channels with best phase noise
and linearity in the industry and offers superior reliability
based on the optimal combination of RF and digital macros
for RADAR processing.
With integrated multi-channel high-resolution ADCs, VCOs,
PLL, PAs, LNAs, phase-shifters, and signal processing
accelerators, the device enables OEMs to significantly reduce
the overall system cost, footprint, and power consumption.
With the support of multi-device aggregation, ultra-wide-
bandwidth, and MIMO processing, the RAA270205 provides
best-in-class angular resolution and range in a very small
form-factor for imaging and autonomous radar applications.
A variety of safety mechanisms such as on chip loop back test,
voltage/clock monitors and sorts of digital error checkers are
implemented in MMIC to satisfy ISO26262 functional safety
requirement.
