CDMA2000 TRANSMIT APPLICATION
To test the compliance to the CDMA2000 base station standard,
an 880 MHz, three-carrier CDMA2000 test model signal
(forward pilot, sync, paging, and six traffic, as per 3GPP2
C.S0010-B, Table 6.5.2.1) was applied to the ADL5330. A cavity-
tuned filter with a 4.6 MHz pass band was used to reduce noise
from the signal source being applied to the device.
Figure 46 shows the spectrum of the output signal under
nominal conditions. Total P
equal to 0.46 dBm and V
channel power ratio is measured in a 30 kHz bandwidth at
750 kHz and 1.98 MHz carrier offset, respectively.
In testing, by holding the gain control voltage steady at 1.4 V,
input power was swept. Figure 47 shows ACPR and noise floor
vs. total output power. Noise floor is measured at 1 MHz
bandwidth at 4 MHz carrier offset.

The results show that up to a total output power of +8 dBm,
ACPR remains in compliance with the standard (<−45 dBc @
750 kHz and <−60 dBc @ 1.98 MHz). At low output power
levels, ACPR at 1.98 MHz carrier offset degrades as the noise
floor of the ADL5330 becomes the dominant contributor to
measured ACPR. Measured noise at 4 MHz carrier offset begins
to increase sharply above 0 dBm output power. This increase is
not due to noise but results from increased carrier-induced
distortion. As output power drops below 0 dBm total, the noise
floor drops towards −85 dBm.
With a fixed input power of −23 dBm, the output power was
again swept by exercising the gain control input. V
swept from 0 V to 1.4 V. The resulting total output power,
ACPR, and noise floor are shown in Figure 48.

standard. As the gain control input drops below 1.0 V, the noise
floor drops below −90 dBm.
SOLDERING INFORMATION
On the underside of the chip scale package, there is an exposed
compressed paddle. This paddle is internally connected to the
chip’s ground. Solder the paddle to the low impedance ground
plane on the printed circuit board to ensure specified electrical
performance and to provide thermal relief. It is also
recommended that the ground planes on all layers under the
paddle be stitched together with vias to reduce thermal
impedance.
