V7 Functional Block Diagram Description M/A-COM’s AM50-0004 is a high dynamic range, GaAs MMIC, low noise amplifier in a low cost, SOIC 8-lead, surface mount, plastic package. It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. The AM50-0004 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The AM50-0004 can operate from any positive supply voltage in the 3 V to 8 V range. Its current can be controlled over a range of 20 mA to 60 mA with an external resistor. The AM50-0004 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 PDC, DCS-1800, DCS-1900 and other PCN/PCS base stations. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed or portable PDC and PCN/PCS systems. The AM50-0004 is fabricated using a low-cost 0.5micron gate length GaAs process. The process features full passivation for increased performance and reliability. The AM50-0004 is 100% RF tested to ensure performance specification compliance.
