HMC-ALH382-SX

Overview

The HMC-ALH382-SX is a GaAs HEMT MMIC low noise amplifier designed for operation between 57 and 65 GHz. It features a small signal gain of 21 dB and a noise figure of 4 dB. The device operates on a 2.5 V supply with a current consumption of 87 mA. It delivers an output power at 1 dB compression (P1dB) of +12 dBm. The component utilizes a die package configuration suitable for surface mount applications.

Feature Summary

• Four-stage GaAs HEMT MMIC architecture providing high dynamic range performance
• Optimized for W-band frequencies ranging from 57 to 65 GHz
• Low noise figure specification supporting sensitive receiver front-ends

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Electronic warfare systems
• High-speed data transmission equipment

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm exact electrical tolerances and testing conditions. Ensure compatibility with existing thermal management solutions due to the die package format. Confirm availability status through authorized distributors as supply levels may vary. Validate that the 2.5V supply requirement aligns with system power constraints before integration.

Selection Notes

Select this component when operating within the 57-65 GHz band requires a balance of high gain and low noise. The 21 dB gain supports direct signal amplification without additional stages in some architectures. Consider the die form factor for custom PCB design or hybrid module integration. Evaluate the 4 dB noise figure against system link budget requirements to ensure adequate sensitivity margins for the intended application environment.
