LTC5553IUDB#TRPBF

RF Mixers Overview

The LTC5553IUDB#TRPBF is a high-performance microwave double-balanced passive mixer designed for frequency upconversion and downconversion applications. It features an integrated RF balun optimized for the 3GHz to 20GHz range and an integrated LO amplifier requiring only 0dBm drive power. The device includes an integrated IF balun covering 500MHz to 9GHz with a single-ended 50Ω interface. Key electrical parameters include a typical conversion loss of 11.6dB, noise figure of 12.8dB, LO/RF isolation of 40dB, and third-order input intercept point (IIP3) of 24.3dBm. It operates on a supply voltage between 3V and 3.6V.

RF Mixers Feature Summary

• Integrates RF and IF baluns to simplify circuit design and reduce component count
• Includes integrated LO amplifier eliminating need for external driver stages
• Provides high linearity performance with superior IIP3 and P1dB specifications

RF Mixers Applications

• Microwave communication systems
• Point-to-point radio links
• Satellite communication equipment

RF Mixers Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the specific variant matches the intended production volume requirements. Ensure compatibility with standard surface mount reflow profiles during the procurement phase to maintain component integrity.

RF Mixers Selection Notes

Select this component when broadband operation from 3GHz to 20GHz is required without external matching networks for the RF port. Consider the integrated LO amplifier if system power budget constraints prevent using external drivers. Evaluate the 12-QFN package dimensions against available PCB real estate constraints before finalizing the design.

RF Mixers Part Context

This part belongs to the LTC5553 series of microwave mixers manufactured by Analog Devices Inc. It is specifically engineered for high-frequency applications where size and integration are critical. The device represents a solution for designers needing wideband performance in a compact footprint compared to discrete mixer solutions.

RF Mixers Replacement Considerations

LTC5553IUDB#PBF is a direct pin-compatible alternative available in tube packaging instead of tape and reel.
