GENERAL DESCRIPTION
The ADL5523 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 ADL5523 amplifier comes in a compact, thermally
enhanced 3x3mm LFCSP package and operates over the
temperature range of −40°C to +85°C.
