APPLICATIONS
CDMA2000, WCDMA, and GSM base station transceivers and
high power amplifiers
GENERAL DESCRIPTION
The ADL5322 is a high linearity GaAs driver amplifier that is
internally matched to 50 Ω for operation in the 700 MHz to
1000 MHz frequency range. The amplifier, which has a gain of
20 dB, is specially designed for use in the output stage of a
cellular base station radio or as an input preamplifier in a
multicarrier base station power amplifier. Matching and biasing
are all on-chip. The ADL5322 is available in a Pb-free, 3mm ×
3 mm, 8-lead LFCSP package with an operating temperature
from −40°C to +85°C.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

BASIC CONNECTIONS
Figure 14 shows the basic connections for operating the
ADL5322. Each of the three power supply lines should be
decoupled with 10 μF, 10 nF, and 100 pF capacitors. Pin 3, Pin 6,
Pin 7, and the exposed paddle under the device should all be
connected to a low impedance ground plane. If multiple ground
planes are being used, these should be stitched together with
vias under the device to optimize thermal conduction. See
recommended land pattern in Figure 12.
CDMA2000 DRIVING APPLICATION
Figure 13 shows a plot of the spectrum of an ADL5323 driving
at 4-carrier CDMA2000 signal at 0 dBm per carrier (total
carrier power = 6 dBm), centered at 880 MHz. At 750 kHz
and 1.98 MHz offset, adjacent channel power ratios of −59 dBc
and −84 dBc (measured in 30 kHz with respect to the 1.22 MHz
carrier) are observed. At 4 MHz carrier offset, −73 dBc is
measured in a 1 MHz bandwidth (−133 dBm/Hz). Note that
the spectrum of the four carriers is slightly rounded due the
frequency response of the cavity-tuned filter that was used to
filter out the noise and distortion of the source signal.

Figure 15 shows how ACP varies with output power level. The
close-in ACP is a function of the signal coding and is unaffected
by output headroom at these power levels. The ACP measured
at 1.98 MHz carrier offset is −72 dBc at 10 dBm output power
(12 dB below the required 60 dBc). At 4 MHz carrier offset, the
noise and distortion measured in a 1 MHz bandwidth is −75 dBm
at 6 dBm (total) output power (0 dBm per carrier). In a 50 dBm
transmitter, this corresponds to an antenna-referred output
power of −31 dBm (1 MHz), which is 18 dB below what is
required by the CDMA2000 standard.

EVALUATION BOARD
Figure 17 shows the schematic of the ADL5322 evaluation
board. The board is powered by a single supply in the 4.75 V to
5.25 V range. The power supply is decoupled on each of the
three power supply pins by 10 μF, 10 nF, and 100 pF capacitors.
See Table 5 for exact evaluation board component values. Note
that all three VCC pins (Pin 1, Pin 2, and Pin 5) should be
independently bypassed as shown in Figure 17 for proper
operation.
