ADL5387
CHARACTERIZATION SETUPS
Figure 60 to Figure 62 show the general characterization bench
setups used extensively for the ADL5387. The setup shown in
Figure 62 was used to do the bulk of the testing and used sinusoidal
signals on both the LO and RF inputs. An automated Agilent-
VEE program was used to control the equipment over the IEEE
bus. This setup was used to measure gain, IP1dB, IIP2, IIP3, I/Q
gain match, and quadrature error. The ADL5387 characterization
board had a 9-to-1 impedance transformer on each of the
differential baseband ports to do the differential-to-single-
ended conversion.
The two setups shown in Figure 60 and Figure 61 were used
for making NF measurements. Figure 60 shows the setup for
measuring NF with no blocker signal applied while Figure 61
was used to measure NF in the presence of a blocker. For both
setups, the noise was measured at a baseband frequency of
Rev. 0 | Page 21 of 28
10 MHz. For the case where a blocker was applied, the output
blocker was at 15 MHz baseband frequency. Note that great care
must be taken when measuring NF in the presence of a blocker.
The RF blocker generator must be filtered to prevent its noise
(which increases with increasing generator output power) from
swamping the noise contribution of the ADL5387. At least
30 dB of attention at the RF and image frequencies is desired.
For example, with a 2xLO of 1848 MHz applied to the ADL5387,
the internal 1xLO is 924 MHz. To obtain a 15 MHz output
blocker signal, the RF blocker generator is set to 939 MHz and
the filters tuned such that there is at least 30 dB of attenuation
from the generator at both the desired RF frequency (934 MHz)
and the image RF frequency (914 MHz). Finally, the blocker
must be removed from the output (by the 10 MHz low-pass
filter) to prevent the blocker from swamping the analyzer.
