CHARACTERIZATION SETUP
EQUIPMENT
The general hardware configuration used for most of the AD8362
characterization is shown in Figure 40. The signal source is a
Rohde & Schwarz SMIQ03B. A 1:4 balun transformer is used to
transform the single-ended RF signal to differential form. For
frequencies above 3.0 GHz, an Agilent 8521A signal source
was used. For the response measurements in Figure 32 and
Figure 33, the configuration shown in Figure 41 is used. For
Figure 34 and Figure 35, the configuration shown in Figure 42
is used. For Figure 36, the configuration shown in Figure 43 is
used.
ANALYSIS
The slope and intercept are derived using the coefficients of
a linear regression performed on data collected in its central
operating range. Error is stated in two forms: error from the
linear response to the CW waveform and output delta from
25°C performance.
The error from linear response to the CW waveform is the
decibel difference in output from the ideal output defined by
the conversion gain and output reference. This is a measure of
the linearity of the device response to both CW and modulated
waveforms. The error in dB is calculated by
where P
Error from the linear response to the CW waveform is not a
measure of absolute accuracy because it is calculated using
the slope and intercept of each device. However, it verifies the
linearity and the effect of modulation on the device response.
Error from the 25°C performance uses the performance of a
given device and waveform type as the reference; it is predomi-
nantly a measurement of output variation with temperature.
