1 MGA-243 Low Noise Amplifier Data Sheet Description Avago Technologies MGA-243 is an economical, easyto-use GaAs MMIC Low Noise Amplifier (LNA), which is designed for use in LNA and driver stages. While a capable /microwave amplifier for any low noise and high linearity.4 to 6 GHz application, the LNA focus is Cellular/PCS base stations. To attain NF min condition, some simple external matching is required. The MGA-243 features a calculated NF min of 1.61 db and 1 db associated gain at 1.9 GHz from a cascode stage, feedback FET amplifier. The input and output are partially matched to be near 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 db with db Gain at 1.9 GHz. With a single.v supply, the LNA typically draws 3 ma. This alignment results in an Intercept Point of. dbm. The MGA-243 is a GaAs MMIC, fabricated using Avago Technologies cost-effective, reliable PHEMT (Pseudomorphic High Electron Mobility Transistor) process. It is housed in the SOT-343 (SC 4-lead) package. This package offers miniature size (1.2 mm by 2. mm), thermal dissipation, and characteristics.
