SSB Setup
Essentially, two primary setups were used to characterize the
AD8345. These setups are shown in Figures 11 and 13. Figure
11 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 were
used to monitor power supply currents and voltages being
supplied to the AD8345 characterization board. Two HP34907
plug-ins were used to provide additional miscellaneous dc and
control signals to the interface board. The LO input was driven
directly by an RF signal generator and the output was 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 12.

Figure 12. Typical SSB Output Spectrum
Modulated Waveform Setup
For evaluating the AD8345 with modulated waveforms, the
setup shown in Figure 13 was used. A Rohde & Schwarz
AMIQ signal generator with differential outputs was used to
generate the baseband signals. For all measurements the input
level on each baseband input pin was 0.7 V
±
0.3 V peak. The
output was measured with a Rohde & Schwarz FSIQ spec-
trum/vector analyzer.
