ADL5602
W-CDMA ACPR PERFORMANCE
Figure 17 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 ADL5602 achieves an ACPR of −75 dBc at −5 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 +5 dBm, ACPR is still very low at −61 dBc, making
the device particularly suitable for PA driver applications.
