Integrated Doppler Radar Module


A rich set of peripherals, flexibility and ease-of-use combined with low power consumption make the RAD-21 module ideal for a wide range of speed measurement and target detection/counting applications typical for Intelligent Transportation Systems and Traffic Calming tasks.

K-Band Bi-Static Doppler transceiver module with built-in Low-Noise Amplifiers (LNAs) and pre-amplifiers for higher sensitivity allows long-range motion detection and reliable target tracking.

RAD-21 boasts:

  • ARM Cortex-M0+ based MCU running up to 48MHz
  • 256KB embedded Flash and 32KB SRAM
  • Low power consumption at <70µA/MHz
  • DMA and Event system
  • Four flexible serial communication modules (SERCOM).
  • Full-Speed USB Device and embedded Host
  • 12-bit ADC for high accuracy DSP
  • Extended temperature range –40 to +105°C
  • High sensitivity and low harmonics emission
  • Multi-step high-end programmable  analog amplifier delivers clear I/Q signals
  • Market-leading power-saving techniques
  • Full set of peripheral interfaces including UART, USB, I2C, SERCOM, Micro SD Card and  GPIO
  • Embedded RTC with calendar and independent backup power supply (10 years guaranteed autonomy
