| RoHS Compliant Low Noise Amplifier 1400 - 2000 MHz Features * * * * * * * * * * Low Noise Figure: 1.6 dB High Input IP3: -6 dBm at 3 V, 6.5 mA bias High Gain: 18 dB Single Supply: +3 to +8 VDC Adjustable current: 3 to 20 mA with external resistor Lead-Free SOT-26 Plastic Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AM50-0006 MAALSS0048 V2 Functional Block Diagram 1 6 2 5 3 4 Description M/A-COM's MAALSS0048 is a high dynamic range, GaAs MMIC, low noise amplifier in a lead-free, SOT-26 miniature surface mount, plastic package. It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. 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.
