Product Details
●The ADL5521 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 ADL5521 provides a high level of integration by incorporating the active bias and dc blocking capacitors, making it very easy to use while not sacrificing design flexibility.
●The ADL5521 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 low power consumption.
●The ADL5521 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.
