ADL5902
LOW FREQUENCY PERFORMANCE
The lowest frequency of operation of the ADL5902 is approxi-
mately 50 MHz. This is the result of the circuit design and
architecture of the ADL5902.
DESCRIPTION OF CHARACTERIZATION
The general hardware configuration used for most of the
ADL5902 characterization is shown in Figure 53. The ADL5902

DATA AND CONTROL
was driven in a single-ended configuration for most character-
ization, except where noted.
Much of the data was taken using an Agilent E4438C signal
source as a RF input stimulus. Several ADL5902 devices
mounted on circuit boards constructed of Rodgers 3006
material were put into a test chamber simultaneously, and a
Keithley S46 RF switching network connected the signal source
to the appropriate device under test. The test chamber
temperature was set to cycle over the appropriate temperature
range. The signal source, switching, and chamber temperature
were all controlled by a PC running Agilent VEE Pro.
The subsequent response to stimulus was measured with a
voltmeter and the results stored in a database for analysis later.
In this way, multiple ADL5902 devices were characterized over
amplitude, frequency, and temperature in a minimum amount
of time. The RF stimulus amplitude was calibrated up to the
circuit board that carries the ADL5902, and, thus, it does not
account for the slight losses due to the connector on the circuit
board that carries the ADL5902 nor for the loss of traces on the
circuit board. For this reason, there is a small absolute amplitude
error (generally <0.5 dB) not accounted for in the characteriza-
tion data, but this is generally not important because the
ADL5902’s relative accuracy is unaffected.
