An integrated millimeter-wave (mmWave) radar-sensing solution, based on Infineon's XENSIV mmWave radar chip has been launched by Arrow Electronics.

This integrated module solution, manufactured by Jorjin Technologies, enables engineers to rapidly deploy detecting and tracking capability of micro and macro motions with high sensitivity and accuracy for developing next-generation smart home and building and healthcare applications. 

According to a recent research report, the radar sensors market is expected to reach $22 billion by 2025, registering a CAGR of around 18 % in the next five years.

The proliferation of radar-sensing technology has been driven by technological advancements and increasing demand for more intuitive presence and motion-detection features to enhance user experience, security, and safety.

Comparing to traditional passive infrared and ultrasonic sensors, mmWave radar-sensing technology offers many performance benefits. 

Radar sensors do not require operating with a direct line of sight, making it possible to be concealed or disguised underneath plywood or plastic enclosures for addressing privacy and security considerations. 

Radar sensing is also highly adaptable to environmental conditions such as darkness, sunshine, smoke, fog, or haze, thus reducing detection errors and improving accuracy.   

This all-in-one integrated solution enables the detection of human presence within a configurable range. 

Micro-movement detection like typing in front of a notebook and macro-movement detection like walking inside a room can be detected.

Powered by Infineon's XENSIV mmWave radar chip and its proprietary radar presence detection algorithms, the solution incorporates a processor system based on Infineon’s ARM Cortex-M4F, an integrated 1Tx/3Rx antenna, and an on-board power regulator. 

The antenna in package (AIP) with built-in detector feature makes it easier for engineers to integrate mmWave radar sensing capability, without prior technical know-how in radio frequency, antenna design or radar signal processing. 

Low power consumption and small-form-factor offer cost-effective benefits.  The solution is FCC pre-test ready.

“Arrow’s extensive sensing technology portfolio, engineering services, and industry expertise help engineers and innovators acquire the kind of technological capabilities it takes to create, make, and manage smart and connected devices.  Infineon’s mmWave radar technology is a great addition to our IoT portfolio.  Our technical collaboration with Jorjin Technologies enables us to bring to market this integrated and ready-to-use module for quick adoption of mmWave radar technology,” said Esmond Wong, Arrow’s vice president of supplier management for the Asia-Pacific region. Jorjin Technologies is a leading module solution provider in Taiwan specialising in AR and IoT. 

“We are excited to work with Infineon and Arrow to facilitate the diffusion of mmWave radar technology into new fields such as smart home, security and even healthcare applications.  With more than 10 years of industry experience, our module design and production expertise help simplify the implementation of mmWave sensor solutions,” said Tom Liang, Chairman of Jorjin Technologies.

To help engineers designing mmWave radar-sensing technology, Arrow now offers the integrated module solution MM5D91-00 and evaluation kit MM5D91E00 from Jorjin Technologies.
