Low Noise Amplifier 1.575 GHz AM50-0002 V 2.00 Features ● ● ● ● ● SO-8 Low Noise Figure: 1.15 dB High Gain: 27 dB Low Power Consumption: 3 to 5 V, 20 mA High Dynamic Range Low Cost SOIC 8 Plastic Package Description M/A-COM's AM50-0002 is a high performance GaAs MMIC low noise amplifier in a low cost SOIC 8-lead surface mount plastic package. The AM50-0002 employs a monolithic 3-stage self-bias design and a simple external matching network to obtain minimum noise figure. It can be biased using 3- or 5-volt supplies. The AM50-0002 is ideally suited for use where low noise figure, high gain, high dynamic range and low power consumption are required. Typical applications include receiver front ends in the Global Positioning System (GPS) market, as well as standard gain blocks, buffer amps, driver amps and IF amps in both fixed and portable systems. Ordering Information Part Number Package AM50-0002 AM50-0002TR AM50-0002RTR AM50-0002SMB M/A-COM's AM50-0002 is fabricated using a mature 0.5micron gate length GaAs process. The process features full passivation for increased performance reliability.
