V1 Functional Block Diagram 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 Lead-Free SOIC-8 Package 100% Matte Tin Plating over Copper Halogen-Free “Green” Mold Compound 260°C Reflow Compatible RoHS* Compliant Version of MAALSS0025 Adjustable current: 20 to 80 mA with external resistor Description M/A-COM’s MAAL-008624 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 MAAL-008624 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The MAAL-008624 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-008624 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 MAAL-008624 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 Technology Solutions Inc.
