LTC5549IUDB#TRMPBF

RF Mixers Overview

The LTC5549IUDB#TRMPBF is a dual-channel passive double-balanced microwave mixer IC from Analog Devices Inc., designed for high-performance radar and RF applications. It operates with an RF frequency range of 2GHz to 14GHz, supporting both up-conversion and down-conversion. The device features an integrated LO buffer amplifier requiring only 0dBm drive power and includes a bypassable internal LO doubler controlled by the X2 digital pin. Key electrical parameters include a conversion loss of 8dB at 5.8GHz, an input P1dB of +14.3dBm, and an OIP3 of 20.2dBm. It utilizes a 12-QFN (3x2) surface-mount package and draws 115mA from a 3V to 3.6V supply.

RF Mixers Feature Summary

• Dual-channel passive double-balanced architecture for simultaneous signal processing
• Integrated LO buffer amplifier eliminates external driver requirements
• Bypassable internal LO doubler simplifies low-frequency PLL integration
• Single-ended 50-ohm ports for simplified circuit matching

RF Mixers Applications

• C, X, and Ku-band radar systems
• Wireless communication infrastructure
• Point-to-point microwave communication equipment
• General-purpose microwave transceivers
• RF test and measurement instruments

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS3 compliance and MSL Level 1 status prior to assembly. Note that this specific part number may have restricted availability or limited stock; check current supply status before finalizing procurement plans. Ensure proper ESD handling procedures are followed during storage and installation.

RF Mixers Selection Notes

Select this component when broadband operation across 2GHz to 14GHz is required in a compact form factor. The integrated LO buffer and doubler reduce bill-of-materials count by minimizing external components. Ideal for designs needing low LO-RF leakage below -30dBm and high linearity. Consider the 12-QFN package constraints for thermal management and PCB layout requirements.

RF Mixers Part Context

This device belongs to the LTC5549 series of microwave mixers. It shares the same 12-QFN footprint as related models like the LTC5548 but offers distinct performance characteristics tailored for radar applications. The '#TRMPBF' suffix indicates tape-and-reel packaging with lead-free finish.
