Fujitsu Components Asia has introduced a 3-channel, 24GHz Doppler radar sensor with a wide speed-detection range and high interference tolerance. The module and evaluation kit facilitates the rapid development and evaluation of various non-contact, movement sensing products even without high-frequency RF electronics expertise. Target applications include human vital sign and fall monitoring, structural and mechanical movement detection, machine maintenance, and more, for the healthcare and industrial markets.

The FWM7RAZ01 supports IF (I/Q) output signals from 1Hz to 1 MHz enabling it to wirelessly detect movement speeds from 6 mm per second to 6 km per second, within a 30-meter range. Although 1 MHz of Doppler Effect is not observable in real-world applications, it is effective for detecting signal interference. To prevent signal overlap, the system can select a different channel and avoid misdetection before it happens.

The FWM7RAZ01 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.

Compared to other detection methods like infrared, ultrasound and laser scan, 24GHz radio waves are more stable and less affected by environmental conditions, such as weather, temperature, illuminance, sound or dirt. The waves also easily penetrate clothing, curtains, glass, and most wooden structures.

These products are available in North America, China and Japan as of January 21, 2020.
