It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. The MAAMSS0045 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The MAAMSS0045 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 MAAMSS0045 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 MAAMSS0045 is fabricated using a low-cost 0.5-micron gate length GaAs process. The process features full passivation for increased performance and reliability. The MAAMSS0045 is 100% RF tested to ensure performance specification compliance.
