AD8341
As the output power drops, the noise floor, measured in dBm in
1 MHz BW at 50 MHz carrier offset, drops slightly.

In this case, adjacent channel power ratio remains constant as
the (noise dominated) alternate channel power degrades
roughly 1-for-1 with output power. As the I and Q control volt-
age drops, the noise floor again drops slowly.
