AWR1843ABGABLRQ1

Overview

The AWR1843ABGABLRQ1 is a single-chip automotive radar system-on-chip (SoC) operating in the 76 GHz to 81 GHz frequency band. It integrates two transmitters and four receivers, supporting Frequency Modulated Continuous Wave (FMCW) radar applications. The device features an ARM Cortex-R4F processor core with a maximum clock frequency of 200 MHz. It includes 576 kB of data RAM and supports high-speed data rates up to 600 Mbps. The component is housed in a 161-ball FC-BGA package measuring 10.4 mm x 10.4 mm. It operates within a temperature range of -40°C to +125°C and meets AEC-Q100 qualification standards for automotive use.

Procurement Notes

Verify that the specific suffix LQ1 or LRQ1 matches the required packaging configuration for your assembly line. Confirm that the component holds valid AEC-Q100 certification for your target automotive grade. Ensure compatibility with existing firmware frameworks designed for the AWR1843 family before finalizing procurement orders.

Selection Notes

Select this component when dual-channel transmission is required for improved angular resolution compared to single-transmitter alternatives. Consider the integrated processor resources if on-chip signal processing is preferred over external host controllers. Evaluate the 161-ball package constraints against your PCB layout density requirements.

Part Context
