Connectors

The BGT60ATR24C shield is an extension board of Infineon's XENSIV™ 60 GHz radar system platform (without a
microcontroller included). The shield must be connected to a microcontroller board, like the Radar Baseboard
MCU7.
The main connector interface of the BGT60ATR24C shield contains two Hirose DF40C-20DP-0.4V connectors. On
the microcontroller side, the Radar Baseboard MCU7 contains the corresponding DF40HC(3.5)-20DS-0.4V(51)
connectors on its bottom side. Figure 5 describes the pin-out and the pad layout of the Hirose connectors on
the BGT60ATR24C shield. To provide the information of the correct digital signal level to the host board, the
line Vdigital is shorted with the 1.8 V supply. The RF shield and the MCU7 board have to be properly aligned, as
depicted in Figure 1.
There is a risk of the Hirose connectors wearing out when regularly plugged into and unplugged from the
shield. To prevent this, it is recommended not to lift the board out of the connector on the short side. Instead,
simply pull on the long side of the board, thereby tilting the short side. This will significantly increase the
operational lifetime of the connectors.

EEPROM

The BGT60ATR24C shield contains an EEPROM memory to store data such as the board identifier. Its
connections can be seen in Figure 6.
