MAX19997AETX+T

RF Mixers Overview

The MAX19997AETX+T is a dual, Silicon Germanium (SiGe) high-linearity downconversion mixer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a wideband frequency range of 1800MHz to 2900MHz and supports conversion up to 23.6GHz. The device integrates dual mixers and dual digital switched attenuators, powered by a 5V supply. Housed in a TQFN-EP-36 surface-mount package, it is designed for applications requiring high gain and linearity.

RF Mixers Procurement Notes

Verify the specific suffix 'G126' or standard tape-and-reel packaging when ordering. Confirm that the TQFN-EP-36 footprint matches the target PCB layout. Ensure the component meets RoHS3 compliance requirements for the intended manufacturing process. Cross-reference the datasheet revision to confirm pinout consistency.

RF Mixers Selection Notes

Select this component for designs requiring integrated attenuation control alongside mixing functions. The SiGe construction offers superior performance compared to standard CMOS alternatives in high-frequency environments. Consider the thermal dissipation properties of the exposed pad in the TQFN-EP-36 package for power management strategies.

RF Mixers Part Context

This part belongs to Maxim Integrated's portfolio of RF and microwave components. It complements other up/down converters and mixers in the product line, providing a specialized solution for multi-band wireless applications. The integration of digital attenuators reduces the need for external control circuitry.

RF Mixers Replacement Considerations

Check for direct cross-reference with MAX19997 variants. Verify compatibility with existing board layouts if substituting with newer revisions. Ensure electrical specifications match the original design requirements before replacement.
