24GHz sensor development kit utilizing Infineon BGT24MTR11 RF transceiver and XMC4200 32-bit ARM® Cortex®-M4 MCU series.
This development kit allows the user to implement and test several sensing applications at the 24GHz ISM band such as FMCW distance measurement, Doppler based movement detection, Doppler based direction of movement detection, and Doppler based speed measurements of targets.
The kit consists of the BGT24MTR11 transceiver MMIC and a XMC4200 32-bit ARM® Cortex®-M4 for signal processing and communication via USB.
The demonstrator board is shown in the figure below highlighting all main board components. The board is already preprogrammed using Infineon’s DAVE™ development tool. The module features a phased locked loop that is controlled with the XMC4200 to generate the FMCW ramps required for distance measurement. The MCU samples up to 2 IF channels of the transceiver chipset and communicates via USB interface to a connected PC.
