ADL5370
The setup used to evaluate baseband frequency sweep and
undesired sideband nulling of the ADL5370 is shown in Figure 39.
The interface board has circuitry that converts the single-ended
I and Q inputs from the arbitrary function generator to differ-
ential I and Q baseband signals with a dc bias of 500 mV.

Undesired sideband nulling was achieved through an iterative
process of adjusting amplitude and phase on the Q channel.
See Sideband Suppression Optimization in the Optimization
section for a more detailed discussion on sideband nulling.
