LT5578IUH#TRPBF

RF Mixers Overview

The LT5578IUH#TRPBF is a high linearity upconverting mixer from Analog Devices, operating within the 400MHz to 2.7GHz frequency range. It features single-ended LO input and RF output ports, simplifying board layout. Key electrical parameters include a typical conversion gain of 1.4dB at 600MHz and -0.7dB at 1.95GHz. The device exhibits an OIP3 of 27dBm at 600MHz and 24.3dBm at 1.95GHz, with a noise figure of 8.6dB. It requires a low LO drive power of -1dBm and operates on a single 3.3V supply with a typical static current of 152mA.

RF Mixers Feature Summary

• Single-ended LO input and RF output architecture reduces system cost and simplifies PCB layout
• Integrated internal LO buffer minimizes required drive power for local oscillator signals
• High linearity performance supports demanding broadband wireless applications
• Compact 24-lead QFN package design facilitates efficient space utilization

RF Mixers Applications

• GSM base station transmitters
• W-CDMA/UMTS infrastructure equipment
• LTE/WiMAX base station upconverters
• Wireless relay systems

RF Mixers Procurement Notes

Verify that the suffix #TRPBF indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the manufacturer part number matches exactly to ensure correct reel specifications and handling requirements. Check for RoHS compliance status as indicated in official documentation. Ensure storage conditions meet semiconductor standards to maintain device integrity prior to assembly.

RF Mixers Selection Notes

Choose this component for designs requiring high dynamic range in upconversion stages across wide bandwidths. The single-ended interface reduces external matching network complexity compared to double-balanced alternatives. Evaluate thermal dissipation capabilities given the 3.3V supply operation. Consider the 24-QFN footprint compatibility with existing board layouts designed for similar Analog Devices mixer families.

RF Mixers Part Context

This part belongs to the LT5578 family of active upconverting mixers designed by Linear Technology, now part of Analog Devices. It complements other variants like the LT5578IUH#PBF which differs primarily in packaging format. The series targets next-generation wireless infrastructure needing improved linearity and simplified integration for multi-standard support.

RF Mixers Replacement Considerations

LT5578IUH#PBF serves as a direct functional substitute differing only in tube versus tape-and-reel packaging configuration.
