CAUTION HOT SURFACE
CONTACT MAY CAUSE BURN
DO NOT TOUCH
Note
RECOMMENDED DUTY CYCLE
: The xWR6843AOPEVM operates at a maximum duty cycle of 50%:
running at a higher duty cycle increases the risk of damaging the EVM by exceeding the maximum
operating junction temperature (T
j
) of 105°C.
Note
This chapter applies to the AWR6843AOPEVM and IWR6843AOPEVM
4.1 Hardware
The xWR6843AOPEVM includes four receivers and three transmitter wide field of antennas on the package of
the device. The IWR6843AOP and AWR6843AOP operate at a 4-Ghz bandwidth from 60 to 64 GHz, with a
maximum output power of 10 dBm; the xWR6843AOPEVM has an antenna gain of ~5 dBi.
Note
The xWR6843AOPEVM has been tested in the 60 - 64GHz band across the temperature range of
-20°C to 60°C.
Note
In accordance to the EN 62311 RF exposure test, a minimum separation distance of 20 centimeters
should be maintained between the user and the EVM during operation.
