MAX9987ETP

Overview

The MAX9987ETP is an RF IC functioning as a local oscillator buffer and splitter, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a frequency range of 700MHz to 1.1GHz, targeting cellular and GSM applications. The device provides 40dB reverse isolation to ensure signal integrity. It is housed in a 20-TQFN (5x5) surface-mount package with an exposed pad for thermal management.

Feature Summary

• Functions as a local oscillator buffer and splitter for RF signal distribution
• Provides high reverse isolation to protect source signals from load variations
• Optimized for cellular and GSM communication system architectures

Applications

• Cellular base station local oscillator distribution
• GSM network infrastructure signal buffering
• RF front-end module LO splitting

Procurement Notes

Verify the specific ordering suffix, such as +T or +, against the manufacturer's official documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the component matches the exact 20-TQFN footprint requirements for your PCB layout. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring precise LO signal distribution within the 700MHz to 1.1GHz band. The 40dB reverse isolation specification is critical for maintaining stability in sensitive RF chains. Consider the 20-TQFN package dimensions for space-constrained mobile and infrastructure designs.

Part Context

This part belongs to the Maxim Integrated RF IC portfolio, specifically designed for wireless communication infrastructure. It addresses the need for reliable local oscillator signal conditioning in modern cellular networks. The device integrates buffer functionality to drive multiple loads while maintaining phase noise performance.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic cross-references may not match the specific 40dB reverse isolation or 700MHz-1.1GHz operational bandwidth required for GSM applications.
