GENERAL DESCRIPTION
The ADL5323 is a high linearity GaAs driver amplifier that is internally matched to 50 Ohms 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 pre-amplifier in a multi-carrier base station power amplifier. Matching, biasing as well as input and output coupling are all on-chip. The ADL5323 is available in a 3mm x 3 mm 8-pin Chip scale package. The ADL5323 is available in a Pb-free 3mm x 3 mm 8-pin Chip Scale Package with an operating temperature of -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.

Preliminary Technical Data EVALUATION BOARD
Figure 3. 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 by a 10 F and a
ADL5323
100 pF capacitors. See table 4 for evaluation board component values. Note that all three Vcc pins (pins 1,2,5) should be independently bypassed as shown above for proper operation.
