AM50-0006

Low Noise Amplifier 1400 - 2000 MHz Features • • • • • Low Noise Figure: 1.6 dB High Input IP3: -6 dBm at 3 V, 6.5 mA bias High Gain: 18 dB Single Supply: +3 to +8 VDC Adjustable current: 3 to 20 mA with external resistor • SOT-26 Plastic Package AM50-0006 V3 Functional Block Diagram Description M/A-COM’s AM50-0006 is a high dynamic range, GaAs MMIC, low noise amplifier in a SOT-26 surface mount plastic package. It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. The AM50-0006 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The AM50-0006 can operate from any positive supply voltage in the 3 V to 8 V range. Its current can be controlled over a range of 3 mA to 20 mA with an external resistor. The AM50-0006 is ideally suited for use where low noise figure, high gain, high dynamic range, and low power consumption are required. Typical applications included receiver front ends in PDC1500, DCS-1800, DCS-1900 and other PCN/PCS applications. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed or portable PDC, PHS, and PCN/PCS systems. The AM50-0006 is fabricated using a low-cost 0.5-micron gate length GaAs process. The process features full passivation for increased performance and reliability. The AM50-0006 is 100% RF tested to ensure performance specification compliance.
