Voltage (V)
Please note that for reliable operation, the evaluation board will have to be mounted to a much
larger heat sink during operation and in laboratory environments to dissipate the power
consumed by the device. The use of a convection fan is also recommended in laboratory
environments.
The area around the module underneath the PCB should not contain any soldermask in order to
maintain good RF grounding.
For proper and safe operation in the laboratory, the power-on sequencing is recommended.
