It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. Pin Configuration Pin No. Pin Name Description 1 VDD Positive supply voltage 2 GND RF and DC Ground 3 RF Output RF Output of the amplifier 4 GND RF and DC Ground 5 REXT CEXT External Current Control By-Pass Capacitor 6 RF Input RF Input of the amplifier The MAALSS0048 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The MAALSS0048 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 MAALSS0048 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 applications. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed or portable PDC and PCN/PCS systems. The MAALSS0048 is fabricated using a low-cost 0.5-micron gate length GaAs process. The process features full passivation for increased performance and reliability. The MAALSS0048 is 100% RF tested to ensure performance specification compliance.
