January 22, 2020 -- Fujitsu Components America has introduced a 3-channel, 24GHz Doppler radar sensor. The module and evaluation kit facilitates the development and evaluation of various non-contact, movement sensing products even without RF electronics expertise.
Target applications include human vital sign and fall monitoring, structural and mechanical movement detection, machine maintenance, and more, for healthcare and industrial markets. The FWM7RAZ01 supports IF (I/Q) output signals from 1Hz to 1 MHz enabling it to detect movement speeds from 6mm-per-second to 6km-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 module measuring 30mm x 44mm x 9.5mm.
