MGA-52543

Agilent Technologies' MGA-52543 is an economical, easy-to-use GaAs MMIC Low Noise Amplifier (LNA), which is designed for use in LNA and driver stages. While a capable RF/microwave amplifier for any low noise and high linearity 0.4 to 6 GHz application, the LNA focus is Cellular/PCS base stations.

To attain NFmin condition, some simple external matching is required. The MGA-52543 features a calculated NFmin of 1.61 dB and 15 dB associated gain at 1.9 GHz froma cascode stage, feedback FET amplifier. The input and output are partially matched to be near 50 .

For base station radio card unit LNA application where better than 2:1 VSWR is required, a series inductor on the input and another series inductor on the output can be added externally. The resulting Noise Figure is typically 1.9 dB with 14 dB Gain at 1.9 GHz. With a single 5.0V supply, the LNA.
