ADL5375
The setup used to evaluate baseband frequency sweep and
undesired sideband nulling of the
The interface board has circuitry that converts the single-ended
I input and Q input from the arbitrary function generator to
differential I and Q baseband signals with a dc bias of 500 mV

(ADL5375-05) or 1500 mV (ADL5375-15). Undesired sideband
nulling was achieved through an iterative process of adjusting
amplitude and phase on the Q-channel. See Sideband
Suppression Optimization section for a detailed description on
sideband nulling.
