It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. Pin Configuration Pin No. Pin Name Description 1 GND RF and DC Ground 2 REXT External Current Control (optional) 3 RFIN RF Input of the amplifier 4 GND RF and DC Ground 5 GND RF and DC Ground 6 RFOUT RF Output of the amplifier 7 VDD Positive supply voltage 8 GND RF and DC Ground The MAAL-008091 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The MAAL-008091 can operate from any supply voltage in the 3 V to 8 V range. Its current can be controlled over a range of 20 mA to 80 mA with an external resistor. The MAAL-008091 is 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 AMPS, GSM, and ETACS base stations. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed and portable cellular and 900 MHz ISM systems. The MAAL-008091 is fabricated using a low-cost 0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability.
