HMC517LC4

Overview

The HMC517LC4 is a GaAs pHEMT MMIC low noise amplifier from Analog Devices Inc., designed for operation within the 17 GHz to 26 GHz frequency range. It provides a typical gain of 19 dB with a noise figure of 2.2 dB. The device operates on a single 3 V supply, drawing approximately 65 mA. Key performance metrics include a P1dB compression point of 11 dBm and an OIP3 of 23 dBm. It features an input return loss of 17 dB and handles a power dissipation of 880 mW. The component is available in a bare die package format.

Feature Summary

• Utilizes GaAs pHEMT technology for high-performance RF amplification
• Engineered for low noise applications in the K/Ka-band spectrum
• Provides stable gain with high linearity characteristics

Applications

• VSAT communication systems
• Point-to-point microwave links
• Military electronic warfare systems
• Test and measurement equipment

Procurement Notes

Verify that the procurement channel supplies genuine Analog Devices components. Confirm the specific package type matches the requirement, as this part number denotes a bare die configuration distinct from packaged variants like the HMC517LC4TR. Ensure handling procedures account for the sensitivity of exposed die components during assembly.

Selection Notes

Select this component when a bare die solution is required for custom substrate integration or advanced packaging techniques. Compare specifications against packaged alternatives if surface-mount convenience is preferred over custom layout flexibility. Validate thermal management capabilities given the 880 mW power dissipation rating in the final application environment.

Part Context

This component belongs to the HMC517G series of low noise amplifiers. It shares core architectural similarities with packaged versions such as the HMC517LC4TR but differs in physical form factor. The series is optimized for wideband applications requiring minimal noise contribution across the 17-26 GHz band.
