HMC571LC5TR

Overview

The HMC571LC5TR is an up/down converter I/Q receiver designed for surface-mount technology, operating within the 21 to 25 GHz frequency range. It utilizes GaAs MMIC technology and is housed in a compact LFCSP-32 package. The device requires a single 3.5 V power supply and draws approximately 125 mA of current. Key performance specifications include a gain of 11 dB, a noise figure of 3 dB, and a P1dB compression point of -6 dBm. It supports an LO frequency of 14 GHz and an IF bandwidth up to 3.5 GHz, with an operating temperature range extending to +85°C.

Feature Summary

• Integrated I/Q downconversion architecture for direct RF-to-baseband processing
• High linearity performance with defined gain and noise characteristics
• Compact surface-mount packaging suitable for dense PCB layouts
• Single-supply operation simplifying power management requirements

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Electronic warfare systems requiring wideband reception
• Test and measurement instrumentation for high-frequency signals

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request original manufacturer datasheets and test reports to confirm electrical parameters match the specified 21-25 GHz operational range. Ensure storage conditions comply with moisture sensitivity levels for LFCSP packages. Validate that the specific suffix corresponds to the reel packaging format required for automated assembly processes.

Selection Notes

Select this component when designing receivers for the 21-25 GHz band requiring integrated I/Q demodulation. Consider the 3.5 V supply constraint and 125 mA current draw for power budgeting. Evaluate the LFCSP-32 footprint against available board space. Compare the 3 dB noise figure and 11 dB gain against system link budget requirements. Ensure the LO drive level at 14 GHz meets the internal mixer requirements for optimal conversion efficiency.

Part Context

This part belongs to the HMC571 series of monolithic microwave integrated circuits (MMICs) from Analog Devices. It is functionally related to the HMC571 bare die variant but offers a pre-packaged solution for easier integration into commercial products. The series targets applications demanding high-frequency performance in a small form factor, distinguishing it from lower-frequency counterparts like the HMC570 which operates in the 17-21 GHz range.

Replacement Considerations

The HMC571 bare die serves as a direct functional alternative for custom packaging solutions. For different frequency bands, consider the HMC570LC5TR for 17-21 GHz operations. Verify pinout compatibility and thermal characteristics when substituting with other LFCSP-32 devices from the same manufacturer family.
