ADL5324
W-CDMA ACPR PERFORMANCE
Figure 38 shows a plot of adjacent channel power ratio (ACPR) vs.
P
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
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 −72 dBc, making the device
particularly suitable for PA driver applications.
