Figure 41. Characterization Bench Setup
The primary setup used to characterize the ADL5372 is shown
in Figure 41. This setup was used to evaluate the product as a
single-sideband modulator. The Aeroflex signal generator supplied
the LO and differential I and Q baseband signals to the device
under test, DUT. The typical LO drive was 0 dBm. The I-channel is
driven by a sine wave, and the Q-channel is driven by a cosine
wave. The lower sideband is the single sideband (SSB) output.
The majority of characterization for the ADL5372 was performed
using a 1 MHz sine wave signal with a 500 mV common-mode
voltage applied to the baseband signals of the DUT. The baseband
signal path was calibrated to ensure that the VIOS and VQOS
offsets on the baseband inputs were minimized, as close as
possible, to 0 V before connecting to the DUT. See the Carrier
Feedthrough Nulling section for the definitions of VIOS and VQOS.
