HMC392LH5

Overview

The HMC392LH5 is a GaAs MMIC Low Noise Amplifier designed for surface mount applications, operating within the 3.5 to 7.0 GHz frequency range. It features a hermetic QFN-12 package and requires a 5 V supply with a typical current draw of 43 mA. Key electrical specifications include a gain of 15.4 dB, a noise figure of 2.5 dB, and an input return loss of 15 dB. The device delivers a P1dB compression point of 14 dBm and an OIP3 of 24.5 dBm, with power dissipation at 629 mW. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes Gallium Arsenide (GaAs) MMIC technology for high-performance RF amplification
• Encapsulated in a hermetic surface-mount package suitable for harsh environments
• Optimized for low noise operation across a wide microwave frequency band

Applications

• Satellite communication systems
• Point-to-point microwave links
• Electronic warfare subsystems

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm lot traceability and hermetic seal integrity upon receipt. Cross-reference datasheet revisions to ensure compatibility with existing design parameters. Validate thermal performance under actual load conditions before final integration.

Selection Notes

Select this component when hermetic sealing is required for environmental protection in SMT designs. Compare against non-hermetic variants like HMC392 if cost or standard packaging suffices. Ensure the 5V supply rail aligns with system power architecture. Verify that the QFN-12 footprint matches PCB layout constraints.

Part Context

Part of the HMC392G series, which includes various package options such as die (HMC392) and leadless packages. The LH5 variant specifically denotes the hermetic QFN-12 configuration, distinguishing it from standard commercial versions intended for less demanding environments.

Replacement Considerations

The HMC392 is listed as a related part but lacks hermetic sealing. No direct public substitute is confirmed; verify functional equivalence with HMC392 only if environmental sealing is not critical.
