W-CDMA ACPR PERFORMANCE
Figure 31 shows a plot of adjacent channel power ratio (ACPR)
vs. P
W-CDMA carrier (Test Model 1−64) at 2140 MHz. This signal
is generated by a very low ACPR source. ACPR is measured at
the output by a high dynamic range spectrum analyzer, which
incorporates an instrument noise correction function.

The ADL5320 achieves an ACPR of −82 dBc at 0 dBm output,
at which point device noise and not distortion is beginning to
dominate the power in the adjacent channels. At an output
power of 10 dBm, ACPR is still very low at −70 dBc making the
device particularly suitable for PA driver applications.
