描述 Description

Calterah Alps 2T4R radar sensor chip (CAL77S224-AE) is an integrated single-chip frequency-modulated continuous wave (FMCW) radar sensor capable of operation in 76- to 81-GHz band. The device is built with advanced low-power 40-nm CMOS process and packaged with low-loss eWLB technology. Its unprecedented level of integration not only significantly simplifies product implementation and development, but also enables extremely compact design. Calterah Alps 2T4R is an ideal solution for ultra-low-power, self-aware, accurate radar sensing applications in the automotive area.

Calterah Alps 2T4R is designed for FMCW radar system with 2 TX and 4 RX. It implements RF system with 2 TX channels, 4 RX channels, built-in Phase Locked Loop (PLL), and analog-to-digital converters (ADCs). It also integrates Calterah radar signal processing subsystem, which implements radar algorithms, including fast Fourier transform (FFT), constant false alarm rate (CFAR) detectors, direction of arrival (DoA) estimators, and other advanced features. The Alps device includes a high-performance and low-power ARC EM6-based processor with exclusive 576-KB memory, which is responsible for radio configuration, baseband control, and other heavyweight application-level algorithms. Simple programming interfaces accommodate a wide variety of radar sensor applications. Additionally, along with the device, a complete radar sensor platform solution is provided, including reference hardware design, semi-turnkey software platform, and user documentation.
