| High Dynamic Range Low Noise Amplifier, 400 - 500 MHz Features * * * * * * Low Noise Figure: 0.9 dB High OIP3: +28 dBm at 5 V, 60 mA bias High Gain: 21 dB Single Supply: +3 to +8 VDC Low Cost SOIC-8 Plastic Package Adjustable current: 20 to 80 mA with external resistor MAALSS0025 V1 Functional Block Diagram GND GND REXT VDD Description M/A-COM's MAALSS0025 is a high dynamic range, low noise GaAs MMIC amplifier in a low cost, surface mount package. It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. The MAALSS0025 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The MAALSS0025 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 MAALSS0025 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 CDMA450 base stations. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed and portable cellular and 450 MHz ISM systems. The MAALSS0025 is fabricated using a low-cost 0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability.

Pin 2 allows use of an external resistor to ground for optional, higher current. For 20 mA operation, no resistor is used. For IDD ~ 40 mA, R2 = 43 ohms; IDD ~ 60 mA, R2 = 15 ohms; IDD ~ 80 mA, R2 = 10 ohms. Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. 2 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
