GND
The ADL5521 is a high performance GaAs pHEMT low-noise
amplifier. It provides high gain and low noise figure for single
down-conversion IF sampling receiver architectures as well as
direct down conversion receivers.

.
The ADL5521 amplifier comes in a compact, thermally
enhanced 3x3mm LFCSP package and operates over the
temperature range 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.
