MGA52543

Agilent MGA-52543 Low Noise Amplifier Data Sheet Features Operating frequency: 0.4 GHz ~ 6.0 GHz Minimum noise figure: 1.61 dB at 1.9 GHz Associated gain : 15 dB at 1.9 GHz Description 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 from a cascode stage, feedback FET amplifier. The input and output are partially matched to be near 50 Ω. Simplified Schematic 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 typically draws 53 mA. This alignment results in an Input Intercept Point of 17.5 dBm. The MGA-52543 is a GaAs MMIC, fabricated using Agilent 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. Vd 5V 360 pF 22 nH 1.9 GHz...
