GSM/EDGE OPERATION
The performance of the ADL5375 in a GSM/EDGE environ-
ment is shown in this section.
Figure 64 illustrates the 6 MHz offset noise of the ADL5375-05
and the ADL5375-15 vs. output power at 940 MHz. Figure 65
demonstrates how the 6 MHz offset noise is affected by varia-
tions in LO drive level for both versions of the ADL5375 at
940 MHz.
W-CDMA OPERATION
The ADL5375 is suitable for W-CDMA operation. Figure 66
and Figure 67 show the adjacent and alternate channel power
ratios for the ADL5375-05 and ADL5375-15, respectively, at an
LO frequency of 2140 MHz.

Figure 66 and Figure 67 show that both versions of the ADL5375
are able to deliver about or better than −72 dB ACPR at an
output power of −10 dBm.
Figure 68 and Figure 69 illustrate the sensitivity of the EVM to
variations in LO drive at 2140 MHz for the ADL5375-05 and
ADL5375-15 respectively.
