Notes:

1. Measured at IEEE® 802.11 specification compliant Error Vector Magnitude (EVM)/Spectral mask

2. Measured after RF matching network (assume 50Ω impedance)

3. RF performance is ensured at 3.3V, 25°C, with a 2-3 dB change at boundary conditions.

4. With respect to TX power, different (higher/lower) RF output power settings can be used for specific antennas and/or

enclosures, in which case, re-certification can be required. Program the custom gain table to control the transmit power

using the MCHPRT3 tool.

5. The availability of some specific channels and/or operational frequency bands are country-dependent and must be

programmed in the host product at the factory to match the intended destination. Regulatory bodies prohibit exposing

the settings to the end user. This requirement needs to be taken care of via host implementation.

6. The host product manufacturer must ensure that the RF behavior adheres to the certification (for example, FCC, ISED)

requirements when the module is installed in the final host product.

7. FCC Radiated Emission limits (Restricted Band)

8. This parameter is characterized but not tested in manufacturing.

9. This parameter is characterized and tested in manufacturing.
