HMC383LC4TR

Overview

The HMC383LC4TR is a medium power RF amplifier manufactured by Analog Devices Inc., designed for surface-mount applications. It operates within a frequency range of 12 GHz to 30 GHz, utilizing GaAs technology in a 24-TFQFN package. The device provides a typical gain of 15 dB with a noise figure of 7.5 dB to 8 dB. It requires a 5 V supply and draws 100 mA of current. Key performance metrics include a P1dB compression point of 16 dBm to 16.5 dBm and an OIP3 of 25 dBm. The input return loss is specified at 11 dB, with a maximum power dissipation of 920 mW.

Feature Summary

• Utilizes Gallium Arsenide (GaAs) technology for high-frequency performance
• Designed as a general-purpose medium power amplifier
• Surface-mount compatible in a compact 24-QFN package

Applications

• GPS receiver front-ends
• Satellite communication systems
• Point-to-point microwave links

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel or cut-tape packaging format. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the revision version aligns with design specifications before finalizing procurement orders.

Selection Notes

Select this component when a wideband amplification solution is needed between 12 GHz and 30 GHz. Consider the 15 dB gain and low noise figure for sensitive receiver stages. Evaluate the 24-QFN footprint against available PCB real estate. Assess thermal management capabilities given the 920 mW power dissipation rating in the chosen enclosure environment.

Part Context

This part belongs to the HMC383G series of RF amplifiers from Analog Devices. It is distinct from evaluation boards like the 122198-HMC383LC4, which are used for testing rather than production. The LC4 suffix indicates the specific package type and manufacturing lot configuration within the broader product family.
