Fujitsu Releases 3-Channel, 24GHz Doppler Radar Sensor Module

February 11, 2020 Perry Cohen

Fujitsu Components America introduced the FWM7RAZ01, a 3-channel, 24GHz Doppler radar sensor with a wide speed-detection range and high interference tolerance. The module and evaluation kit facilitate the development and evaluation of various non-contact, movement sensing products even without high-frequency RF electronics expertise. Applications that can be integrated into the sensors include human vital sign and fall monitoring, structural and mechanical movement detection, machine maintenance, and more.

The FWM7RAZ01 supports IF (I/Q) output signals from 1Hz to 1 MHz enabling it to wirelessly detect movement speeds from 6mm-per-second to 6km-per- second, within a 30-meter range.

The Doppler radar sensor consists of a 24GHz transceiver, TX and RX array antennas, IF amplifier, MCU, DAC, E2PROM and an LDO voltage regulator all integrated into a single, compact module measuring 30mm x 44mm x 9.5mm. Pin header terminals positioned on the back of the module simplify integration, even for designers who aren’t familiar with high-frequency circuits.

Samples of the FWM7RAZ01 Doppler radar sensor and evaluation kit will be available in February 2020.
