Figure 39. Setup for Baseband Frequency Sweep and Undesired Sideband Nulling

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.
