The ADL5323 is a high linearity GaAs driver amplifier that is
internally matched to 50 Ω for operation in the 1700 MHz to
2400 MHz frequency range. The amplifier, which has a gain of
20 dB, has been 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 ADL5323 is available in a Pb-free, 3 mm ×
3 mm, 8-lead LFCSP with an operating temperature of
−40°C to +85°C.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
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 17 shows the basic connections for operating the
ADL5323. 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 the
recommended land pattern in Figure 14 for more information.

EVALUATION BOARD
06058-016
Figure 19 shows the schematic of the ADL5323 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 the 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 19 for proper
operation.
