EBV & Infineon - 24 GHz


The SMR-31x, SMR-32x and SMR-33x are K-Band based motion detectors. The ultra-small devices will be delivered directly on tape for mounting within a standard SMT. Due to the pulse capability the sensors are also suitable for low-power applications.


  • The SMR series offers a unique combination of high functionality, low power consumption, cost efficiency and very easy installation.
  • Speeds-up time to market with a turnkey solution, reducing design effort and investment on complex algorithm development.
  • Determines not only motion but also speed and direction of movement of the detected object – a clear advantage over PIR technology.
  • Offers increased sensitivity vs.
  • PIR even in coverage of large areas.
  • Eases integration even in the smallest space available.


  • Radar-based motion detector working in the 24 GHz frequency range.
  • Integrated Doppler software
  • Extended temperature range from -40° C up to +85° C.
  • SMT outline dimensions:
  • 20 mm x 15 mm x 3 mm.  
  • All SMR modules are compliant to ETSI 300 440.
