MAX2640AUT/V+T

RF Amplifiers Overview

The MAX2640AUT/V+T is a SiGe ultra-low-noise amplifier designed for operation between 300 MHz and 1.5 GHz, with some documentation extending the range to 2500 MHz. It features a gain of 15.1 dB and operates on a supply voltage ranging from 2.7 V to 5.5 V. The typical operating supply current is 3.5 mA, while specific test conditions at 900 MHz indicate a current draw of 7.8 mA. The device utilizes an SOT-23-6 surface-mount package.

RF Amplifiers Feature Summary

RF Amplifiers Procurement Notes

Verify the exact suffix (e.g., +T vs /V+T) against the manufacturer's official ordering guide to ensure correct tape-and-reel packaging and temperature grade specifications. Confirm that the component meets RoHS compliance requirements if mandated by your project standards. Cross-reference the datasheet revision date to ensure compatibility with current design parameters.

RF Amplifiers Selection Notes

Select this component when a low noise figure is critical within the 300 MHz to 1.5 GHz band. Consider the SOT-23-6 package size constraints for PCB layout. Evaluate the 7.8 mA supply current requirement against system power budgets. Ensure the input impedance matches the preceding stage to minimize signal reflection and maintain optimal noise performance.

RF Amplifiers Part Context

This part belongs to Maxim Integrated's family of SiGe MMIC amplifiers. These components are engineered for high linearity and low noise in compact packages. The MAX2640 series specifically targets applications requiring reliable amplification in mobile and base station environments without excessive power consumption.

RF Amplifiers Replacement Considerations

Direct substitutes include other SiGe LNAs from Analog Devices/Maxim with similar SOT-23-6 footprints and comparable gain/noise figures. Verify pin-to-pin compatibility and electrical parameter overlap before substitution.
