The ADL5523 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 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 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 comes in a compact, thermally enhanced, 3 mm × …
