About

Precise sensing with 24 GHz mmWave radar sensors

Infineon’s wide portfolio of 24 GHz radar sensors includes Doppler radar sensors as well as FMCW radar systems that can detect motion, and determine the direction of motion, speed, and depending on the antenna configuration, angle of arrival as well as position of single and multiple targets. These capabilities are ideally suited for applications such as indoor and outdoor lighting, cameras, doorbells and smart security devices, automated doors, and navigation features in multicopters and service robots.

XENSIV™ 24 GHz radar sensing solutions

Infineon's XENSIV™ 24 GHz transceivers provide a comprehensive portfolio of highly integrated solutions, offering a range of transmitter (Tx) and receiver (Rx) channel configurations. Key products include:

  • BGT24LTR11: 1 Tx, 1 Rx – The smallest 24 GHz MMIC on the market
  • BGT24LTR22: 2 Tx, 2 Rx – A MMIC that enables advanced tracking functionalities

These XENSIV™ 24 GHz transceivers also deliver exceptional power efficiency, with power consumption values of less than 1 mW achievable through duty-cycling.

  • Detection Range: Infineon’s 24 GHz transceivers enable long-range motion detection and distance measurements. Distances of up to 100 m can be covered, which makes them ideal for outdoor areas or industrial applications which require long-range detection capabilities.
  • Customization: Depending on the individual antenna design, detection range and field of view can be defined. By deploying more receiving channels, accurate position of a single or multiple targets can be tracked. 
  • Cost-efficient: 24 GHz modules can be designed cost-effectively.
  • Robustness: 24 GHz sensors are less sensitive to changes in environmental conditions such as temperature, humidity, fog, dust, ambient light, etc. than many other sensors.
  • Obstruction: For detection through non-conductive obstacles or if thick product housing materials are applied, 24 GHz sensors are a good choice since they get less attenuated than higher frequencies.
  • Regulation: The 24 GHz ISM range is clearly and uniformly regulated worldwide.
  • Established technology: 24 GHz radar sensors have been used in industrial and automotive applications for around 20 years.
