Data Sheet FEATURES Operation from 400 MHz to 4000 MHz Noise figure of 0.8 dB at 900 MHz Requires few external components Integrated active bias control circuit Integrated dc blocking capacitors Adjustable bias for low power applications Single-supply operation from 3 V to 5 V Gain of 21.5 dB at 900 MHz OIP3 of 34.0 dBm at 900 MHz P1dB of 21.0 dBm at 900 MHz Small footprint LFCSP Pin-compatible version with 20.8 dB gain available GENERAL DESCRIPTION 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 not sacrificing design flexibility. 400 MHz to 4000 MHz Low Noise Amplifier ADL5523 FUNCTIONAL BLOCK DIAGRAM VBIAS 1 RFIN 2 ACTIVE BIAS 8 VPOS 7 RFOUT NC 3 NC 4 ADL5523 6 NC 5 NC NC = NO CONNECT Figure 1. 06829-001 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. Rev.
