9.4.2 IEEE 802.11 Transmitter Performance
The transmitter performance under nominal conditions are:
- VBAT = 3.3V
- VDDIO = 3.3V
- Temp = 25°C
- Measured after DC blocking capacitor (C19) as in Reference Design

Note:
- Measured at IEEE 802.11 specification compliant EVM/Spectral mask.
- Measured after DC blocking capacitor (C19) as in Reference Design.
- Operating temperature range is -40°C to +85°C. RF performance is assured at a room temperature of 25°C with a 2-3 dB change at boundary conditions.
- With respect to TX power, different (higher/lower) RF output power settings may be used for specific antennas and/or enclosures, in which case, recertification may be required.
- The availability of some specific channels and/or operational frequency bands are country-dependent and should be programmed at the host product 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.
