LTC5553IUDB#TRMPBF

RF Mixers Overview

The LTC5553IUDB#TRMPBF is a high-performance microwave double-balanced passive mixer manufactured by Analog Devices Inc. It operates within an RF frequency range of 3 GHz to 20 GHz and supports LO frequencies from 1 GHz to 20 GHz. The device features an integrated LO amplifier requiring only 0 dBm drive power, alongside integrated RF and IF baluns. Key electrical parameters include a maximum conversion loss of 11.6 dB, a typical noise figure of 12.8 dB, and a third-order input intercept point (OIP3) of 21.5 dBm. It functions on a 3.3 V supply with a current draw of 132 mA, delivering a P1dB of 16 dBm across an IF range of 500 MHz to 9 GHz.

RF Mixers Feature Summary

• Integrates an LO amplifier optimized for 1 GHz to 20 GHz operation, eliminating the need for external driver circuitry.
• Includes integrated RF and IF baluns to simplify board layout and provide single-ended 50-ohm interfaces.
• Delivers high linearity performance with superior IIP3 and P1dB specifications for demanding signal processing.
• Supports both frequency upconversion and downconversion applications in a compact surface-mount package.

RF Mixers Applications

• Microwave communication systems
• Point-to-point radio links
• Radar receiver front-ends

RF Mixers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the specific suffix matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS directives and check for any regional distribution restrictions prior to finalizing procurement orders.

RF Mixers Selection Notes

Select this component when wideband coverage from 3 GHz to 20 GHz is required without external LO drivers. Consider the integrated balun architecture for simplified design and reduced component count. Evaluate the 11.6 dB conversion loss against system link budget requirements and verify thermal management capabilities for continuous operation at elevated temperatures.

RF Mixers Part Context

This part belongs to the LTC5553 series of microwave mixers designed for high-frequency wireless infrastructure. It shares the QFN-12 package form factor with other devices in the family but offers distinct frequency ranges and integration levels compared to variants like the LTC5548 or LTC5549.
