ADL5523 Low Noise Amplifier

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 provides a high level of integration by incorporating the active bias and the dc blocking capacitors, making it very easy to use while .
