HMC-ALH311-SX

Overview

The HMC-ALH311-SX is a GaAs MMIC HEMT low noise driver amplifier die from Analog Devices Inc. It operates within the frequency range of 22 to 26.5 GHz. The component provides 25 dB of gain and features a typical noise figure of 3 dB at 25 GHz. It delivers an output power of +12 dBm at the 1 dB compression point. The device is designed for surface mount installation in a die package configuration.

Feature Summary

• Utilizes GaAs MMIC HEMT technology for high-performance amplification
• Functions as a low noise driver amplifier with significant gain capability
• Engineered for operation in the W-band frequency spectrum

Applications

• W-band communication systems
• Satellite communication links
• Point-to-point microwave radio systems

Procurement Notes

Verify availability status directly with Analog Devices or authorized distributors, as supply conditions may vary. Confirm that the die package format aligns with your assembly capabilities. Ensure compliance with RoHS standards if required by your specific application regulations. Request official datasheets for precise electrical characterization before integration into design prototypes.

Selection Notes

Select this component when a high-gain, low-noise solution is required for frequencies between 22 and 26.5 GHz. Consider the die form factor for custom packaging solutions. Evaluate the 25 dB gain against system link budget requirements. Assess the thermal management needs associated with the GaAs HEMT technology in your final enclosure design.

Part Context

This part belongs to the HMC-ALH series of low noise amplifiers from Analog Devices. It is specifically optimized for W-band applications requiring high linearity and low noise figures. The -SX suffix typically denotes a specific tape-and-reel or die handling configuration, though verification is recommended. It serves as a critical active element in RF front-end chains.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct replacements or pin-compatible alternatives suitable for W-band operations.
