MGA-52543 Low Noise Amplifier Data Sheet Description Avago Technologies’ MGA-52543 is an economical, easyto-use Ga As 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 NF condition, some simple external matching is min required. The MGA-52543 Features a calculated NF of 1.61 min d B and 15 d B associated gain at 1.9 GHz from a cascode stage, feedback FET amplifier. The input and output are partially matched to be near 50 Ω. 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 d B with 14 d B Gain at 1.9 GHz. With a single 5.0V supply, the LNA typically draws 53 m A. This alignment results in an Input Intercept Point of 17.5 d Bm. The MGA-52543 is a Ga As MMIC, fabricated using Avago Technologies’ cost-effective, reliable PHEMT (Pseudomorphic High Electron Mobility Transistor) process. It is housed in the SOT-343 (SC70 4-lead) package. This package offers miniature size (1.2 mm by 2.0 mm), thermal dissipation, and RF characteristics.
