Description
M/A-COM s AM50-0006is a high dynamic range,GaAs MMIC,low noise amplifier in a low cost,SOT-26miniature surface mount,plastic package.It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility.The AM50-0006also features flexible biasing to control the current consumption vs.dynamic range trade-off.The AM50-0006can operate from any positive supply voltage in the 3V to 8V range.Its current can be controlled over a range of 3mA to 20mA with an external resistor.
The AM50-0006is 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 PDC-1500,DCS-1800,DCS-1900,PHS and other PCN/PCS applications.It is also useful as a gain block,buffer,driver and IF amplifier in both fixed and portable PDC,PHS,and PCN/PCS systems.
The AM50-0006is fabricated using a low-cost 0.5-micron gate length GaAs process.The process features full passivation for increased performance reliability.The AM50-0006is 100%RF tested to ensure performance specification compliance.
