PCB Storage and Handling Recommendations
The immersion silver finish of the PCB provides a better high-frequency performance but is also prone to
oxidation in an open environment. This oxidation causes the surface around the antenna region to
blacken. To avoid this effect, store the PCB in an ESD cover and keep it at controlled room temperature
with low humidity conditions. All ESD precautions must be taken while using and handling the EVM.

Regulatory Information
The IWR1443 evaluation module (IWR1443BOOST) is in compliance with Directive 2014/53/EU. The full
text of TI's EU Declaration of Conformity is available
.
The compliance has been verified in the operating bands 76 – 77 GHz and 77 – 81 GHz. Should the user
choose to configure the EVM to operate outside the test conditions, it should be operated inside a
protected or controlled environment, such as a shielded chamber. This evaluation board is intended only
for development, and is not for use in an end product or part of an end product. Developers and
integrators that incorporate the chipset in any end products are responsible for obtaining applicable
regulatory approvals for such an end product.
The European RF exposure radiation limit is fulfilled if a minimum distance of 5 cm between the users
body and the radio transmitter is respected.
NOTE:
The EUT has been tested in the 76 – 77 GHz band (2 Tx at a time) at a maximum peak
power of 26 dBm EIRP, and in the 77 – 81 GHz band (1 Tx at a time) with maximum peak
power of 21 dBm EIRP across the temperature range of –20ºC to 60ºC.

Troubleshooting
EVM board power-up failure: refer to
for desired power connections. Both the NRST and 5-V
LEDs should glow brightly. When a non-functional or non-sufficient current capacity power supply is used
with this EVM, the EVM LEDs do not turn on. Refer to
for LED information.
