ADL5330
WCDMA TRANSMIT APPLICATION
Figure 43 shows a plot of the output spectrum of the ADL5330
transmitting a single-carrier WCDMA signal (Test Model 1-64
at 2140 MHz). The carrier power output is approximately
−9.6 dBm. The gain control voltage is equal to 1.4 V giving a
gain of approximately 14.4 dB. At this power level, an adjacent
channel power ratio of −65.61 dBc is achieved. The alternate
channel power ratio of −71.37 dBc is dominated by the noise
floor of the ADL5330.
Figure 44 shows how ACPR and noise vary with different input
power levels (gain control voltage is held at 1.4 V). At high
power levels, both adjacent and alternate channel power ratios
sharply increase. As output power drops, adjacent and alternate
channel power ratios both reach minima before the measure-
ment becomes dominated by the noise floor of the ADL5330. At
this point, adjacent and alternate channel power ratios become
approximately equal.
As the output power drops, the noise floor, measured in dBm/
Hz at 50 MHz carrier offset, initially falls and then levels off.
