Product Brief
Distance2Go development kit
24 GHz 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 24 GHz 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.
A block diagram of the demonstrator board is shown in the figure below highlighting all main
board components. The board is already preprogrammed using Infineon’s DAVE™ develop-
ment 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.
A provided PC application GUI (Windows XP/Vista/7/8) can be used to display and analyze
acquired data in time and frequency domain. The GUI allows for the extraction of the radar
time domain signals allowing for advanced debugging and algorithm development.
