4.5 Transmitter Performance
The following are the typical conditions for radio transmitter performance:
VBATT at 3.3V, VDDIO at 3.3V, temperature at 25°C and WLAN Channel 6 (2437 MHz).
The following table provides the transmitter performance characteristics for the module.

Note:
- Measured at 802.11 spec compliant EVM/Spectral Mask.
- Measured at RF balun output.
- Operating temperature range is -40°C to +85°C. RF performance is assured at room temperature of 25°C with a 2-3 dB change at boundary conditions.
- Measured at 11 Mbps, DG (Digital Gain) = -7, WLAN Channel 6 (2437 MHz).
- 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 must 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.
- The RF parameters for the ATWILC1000-MR110UB will be approximately 1 dB less than the values in the table. This insertion loss accounts for PCB trace losses and the filter network loss to the U.FL connector.
