CHARACTERIZATION SETUPS
SSB SETUP
Two main setups were used to characterize this product. These
setups are shown in Figure 33 and Figure 35. Figure 33 shows
the setup used to evaluate the product as an SSB. The AD8346
motherboard had circuitry that converted the single-ended
I and Q inputs from the arbitrary function generator to differ-
ential inputs with a dc bias of approximately 1.2 V. In addition,
the motherboard also provided 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 AD8346 evaluation board (a full schematic of

the AD8346 evaluation board can be found in Figure 30).
The two HP34907 plug-ins were used to provide additional
miscellaneous dc and control signals to the motherboard. The
LO was driven by an RF signal generator (through the balun on
the evaluation board to present a differential LO signal to the
device) and the output was measured 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 34.
