APPLICATIONS
Multi carrier and digital wireless base station infrastructure CDMA and CDMA2000 base stations BTS equipment such as High Power Amplifiers (HPA's) and pre-drivers.
GENERAL DESCRIPTION
The ADL5322 is a high linearity GaAs driver amplifier that is internally matched to 50 Ohms for operation in the 700 MHz to 1000 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 pre-amplifier in a multi-carrier base station power amplifier. Matching, biasing as well as input and output coupling capacitors are all on-chip. The ADL5322 is available in a Pb-free 3mm x 3 mm 8-pin Chip scale package with an operating temperature from -40C to +85C.

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.
