GENERAL DESCRIPTION
The ADL5523 is a high performance GaAs pHEMT low noise
amplifier. It provides high gain and low noise figure for single-
downconversion IF sampling receiver architectures as well as
direct-downconversion receivers.
The ADL5523 provides a high level of integration by incorporating
the active bias and the dc blocking capacitors, making it very
easy to use while not sacrificing design flexibility.
The ADL5523 is easy to tune, requiring only a few external
components. The device can support operation from 3 V to 5 V,
and the current draw can be adjusted with the external bias
resistor for applications requiring very low power consumption.
The ADL5523 comes in a compact, thermally enhanced, 3 mm ×
3 mm LFCSP and operates over the temperature range of −40°C
to +85C.
A fully populated evaluation board is also available.
