Is it related to Power Level? It appears only at Low power?
It may be possible that PA switches between power mode. When designingPA, due to efficiency requirement, PA will switch to high power modeHPM or low power mode LPM. When PA switches, it may cause sometransient peak, and phase also jumps which is more problematic if itappears on useful part of data.
