a. This specification row indicates the linear power specification as measured from the chip output port. The
requirement is in dBm (TX power). The ratio (dB) in the Conditions/Notes column is the EVM.
b. This specification row indicates the EVM floor. The requirement is in dB (EVM). The power in the Conditions/
Notes column is the TX power specification in dBm.
General Spurious Emissions Specifications
This section provides the TX and RX spurious emissions specifications for the WLAN 2.4 GHz and 5 GHz
bands. The recommended spectrum analyzer settings for the spurious emissions specifications are provided in
Table 27.
