CHARACTERIZATION SETUP
The primary setup used to characterize the ADL5592 is shown
in Figure 23. This setup was used to measure the frequency
response, linearity, and output compression of the amplifier. A
Rohde & Schwarz SMT 03 signal generator was used to drive
the amplifier with a 4 dBm input. The output of the ADL5592
was connected to a Rohde & Schwarz FSIQ7 spectrum analyzer
through an RF switch matrix unit. For the linearity measurement,
two SMT 03 signal generators were used to generate the two-tone
RF input signal. (The same SMT 03 is used for both amplifier

and mixer characterization.) The gain control data was generated
by a Tektronix DG2020A data generator. The DG2020A generated
all three of the SPI input signals: CLK, DATA, and LE. A separate
SMT 03 was used to generate the mixer local oscillator signal
(LO input signal) when the loopback mixer was enabled. An
Agilent Visual Engineering Environment (VEE) program
controlled the test instruments through the general-purpose
interface bus (GPIB) interface.
