CHARACTERIZATION SETUPS
SSB SETUP
Essentially, two primary setups are used to characterize the
AD8345. These setups are shown in Figure 37 and Figure 38.
Figure 37 shows the setup used to evaluate the product as a
single sideband modulator. The interface board converts the
single-ended I and Q inputs from the arbitrary function
generator to differential inputs with a dc bias of approximately
0.7 V. The interface board also provides connections for power
supply routing. The HP34970A and its associated plug-in 34901
are used to monitor power supply currents and voltages being
supplied to the AD8345 characterization board. Two HP34907
plug-ins are used to provide additional miscellaneous dc and
control signals to the interface board. The LO inputs are driven
directly by an RF signal generator, and the output is measured
directly with a spectrum analyzer. With the I channel driven
with a sine wave and the Q channel driven with a cosine wave,
the lower sideband is the single sideband output. The typical
SSB output spectrum is shown in Figure 36.
