RF Amplifiers Procurement Notes

Verify current availability status as the component may be discontinued or subject to supply restrictions. Confirm RoHS compliance and lead times with authorized distributors. Ensure the specific suffix matches the required packaging format. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with design requirements before procurement.

RF Amplifiers Selection Notes

Select this component for applications requiring dual-band amplification in the 900 MHz and 1.8 GHz ranges. Consider the variable gain feature if dynamic range adjustment is necessary. Evaluate the noise figure and gain specifications against system link budget requirements. Ensure the 10-pin uMAX package fits the PCB layout constraints. Verify thermal performance within the specified operating temperature range.

RF Amplifiers Part Context

The MAX2652EUB belongs to the Maxim Integrated RF amplifier family, specifically engineered for cellular and positioning systems. It addresses the need for compact, high-performance LNAs in multi-standard mobile devices. The device integrates dual channels into a single small footprint, reducing board space compared to discrete solutions. It supports both DCS and PCS bands simultaneously.

RF Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct replacements within the MAX26xx series or consult Analog Devices for obsolescence notices. Verify compatibility of pinouts and electrical parameters if considering alternative dual-band LNAs.
