K-MC1_LP Low Power Radar Transceiver

Key Features:
  • Vcc 3.3V .. 5V
  • 25°x12° Pattern
  • 24GHz K-band
  • I/Q Mixer
  • IF-Preamp


K-MC1_LP is a low current doppler module with an asymmetrical narrow beam for medium to long distance sensors. It is ideally suited for traffic applicatons.

K-MC1_LP needs 10 times less current than our standard K-MC1 sensor and works from 3.3V or 5V power supplies at nearly the same detection sensitivity.
This module includes an RF low noise amplifier and two 47dB IF pre-amplifiers for both I and Q channels. The need for external analogue electronics will be significantly reduced by this feature.
Please note, that K-MC1_LP does not provide a VCO: FMCW and FSK is not possible.

Enegery Saving ++
Is your equipment battery or solar cell operated?
K-MC1_LP and K-MC5_LP work with ONLY 30mW supply power!
Users needing FMCW or FSK feature can still use our standard series sensors.
K-MC1 and K-MC3 Modules are equipped with a power saving technology: Rapid Sleep Wakeup.
RSW allows power savings up to 90% and more.
