The new 77 GHz Radar Chipset for ADAS from NXP/FreescaleSiGe:C xHBT technology & Fan-Out RCP Wafer-Level Packaging
In 2015 NXP (formerly Freescale), a leader in integrated circuits for ADAS 77 GHz radar, introduced a new chipset for complete system-level radar solutions using Freescale’s new Fan-Out RCP packaging. This transceiver chipset is scalable for multi-channel operation and enables a single radar platform with electronic beam steering and wide field-of-view for auto safety, communications infrastructure, and industrial systems.
In 2015, Continental announced that its current-generation ARS 400 long-range radar sensor incorporates Freescale’s MR2001 77 GHz multichannel radar transceiver and MPC577xK microcontroller, with integrated radar signal ADCs and a dedicated radar DSP. The entire chipset uses RCP, the Fan-Out Wafer Level Package developed by Freescale.
This package’s lack of wire bonding reduces inductance, and it’s designed specifically for increased heat management. And thanks to Freescale’s innovative approach, the RCP package is robust enough to be installed in a front automotive module.
The radar dies are manufactured with the newest and most advanced process from NXP/Freescale, merging RF-Transistor SiGe:C xHBT and a 0.18 µm CMOS transistor.This report includes a complete analysis of the entire MR2001 chipset (MR2001RVK Receiver, MR2001TVK transmitter, and MR2001VVK VCO components).
This report also features a full comparison with the Infineon 77 GHz radar chipset that’s included in the Bosch MRR1Plus. Additionally, a complete comparison is provided between Infineon’s Fan-Out eWLB and NXP/Freescale’s Fan-Out RCP packaging, including technical choice and the result on the process flow.
