O83 0688 FT 28 gare M/A-COM’s AMS50-0003 is a high dynamic range, GaAs MMIC, 3 TR low noise amplifier in a low cost, SOIC 8-lead, surface mount, plastic comm = —! package. {It employs external input matching to obtain optimum Geom | 013/020 (8 PL | L cirial noise figure performance and operating frequency flexibility. The oe ome, AMS50-0003 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The AMS50-0003 can operate from any supply voltage in the 3 V to 8 V range. Its current can be controlled over a range of 20 mA to 80 mA with an extemal Tesistor. The AMS0-0003 is ideally suited for use where low noise figure. Ordering Information high gain, high dynamic range, and low power consumption are required. Typical applications include receiver front ends in AMPS, ; GSM and ETACS base stations. It is also useful as a gain block, AM50-0003 SOIC 8-Lead Plastic buffer. driver and IF amplifier in both fixed and portable cellular and AM50-0003TR Forward Tape and Reel” 900 MHz ISM systems. AMS50-0003RTR Reverse Tape and Reel” The AMS0-0003 is fabricated using a low-cost 0.5-micron gate AMS50-0003SMB Designer's Kit length GaAs process. The process features full passivation for * If specific reel size is required, consult factory for part number increased performance reliability. The AM50-0003 is 100% RF assignment tested to ensure performance specification compliance.
