06828-001 FEATURES Figure 1. GENERAL DESCRIPTION
The ADL5521 is a high performance GaAs pHEMT low noise
amplifier. It provides high gain and low noise figure for singledownconversion IF sampling receiver architectures as well as
direct-downconversion receivers. The ADL5521 is easy to tune, requiring only a few external
components. The device can support operation from 3 V to 5 V, …
