HMC517LC4TR

Overview

The HMC517LC4TR is a low noise amplifier from Analog Devices, operating within the 17 GHz to 26 GHz frequency range. It utilizes GaAs technology and is housed in a 24-TFQFN (4x4 mm) surface-mount package with an exposed pad. The device requires a single 3 V supply voltage and draws 67 mA of current. Key electrical specifications include a typical gain of 19 dB, a noise figure of 2.5 dB, a P1dB compression point of 13 dBm, and an OIP3 of 23 dBm. It functions as a general-purpose RF amplifier suitable for high-frequency signal chain applications.

Feature Summary

• Provides low noise amplification across the 17 GHz to 26 GHz band
• Integrates high linearity performance with a 23 dBm output third-order intercept point
• Operates on a single 3 V power supply with moderate current consumption
• Features a compact 24-lead QFN footprint for efficient board space utilization

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Test and measurement instrumentation front ends
• Military electronic warfare systems

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the received parts match the specific HMC517LC4TR designation and packaging type. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions prior to final design integration. Ensure compliance with RoHS3 standards and handle according to moisture sensitivity level 3 requirements during storage and assembly processes.

Selection Notes

Select this component when designing circuits requiring low noise figures below 3 dB at frequencies above 17 GHz. Consider the 19 dB gain profile for intermediate stage amplification rather than initial antenna reception stages. Evaluate thermal management capabilities due to the exposed pad requirement for heat dissipation. Compare against alternative GaAs amplifiers if higher output power or different supply voltages are necessary for the specific system architecture.
