| Low Noise Amplifier 1.575 GHz Features * * * * * Low Noise Figure: 1.15 dB High Gain: 27 dB Low Power Consumption: 5V, 20 mA High Dynamic Range SOIC-8 Package AM50-0002 V8 Functional Diagram GND GND RF IN GND Description M/A-COM's AM50-0002 is a high performance GaAs MMIC low noise amplifier in a 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. 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. M/A-COM'S AM50-0002 is fabricated using a mature 0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability.
