GENERAL DESCRIPTION
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.

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.
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.
