HMC-ALH244-SX

Overview

The HMC-ALH244-SX is a two-stage GaAs MMIC HEMT low-noise amplifier chip designed for the W-band frequency range of 24 GHz to 40 GHz. It provides a gain of 12 dB and a noise figure of 3.5 dB. The device operates on a +4 V supply voltage with a current consumption of 45 mA, resulting in low power dissipation. Packaged as a die for surface-mount applications, it supports high-frequency signal amplification with efficient energy usage.

Feature Summary

• Two-stage GaAs MMIC HEMT architecture for enhanced performance
• Optimized for W-band operation between 24 GHz and 40 GHz
• Low power consumption with 45 mA current draw at 4 V

Applications

• W-band communication systems
• High-frequency radar receivers
• Satellite ground station equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the received die matches the specified package type and lot codes. Request official datasheets and test reports to ensure compliance with electrical parameters before integration into production designs.

Selection Notes

Select this component when designing circuits requiring low noise figures below 4 dB in the 24–40 GHz range. Consider the 12 dB gain and 45 mA power profile for thermal management. Ensure the design accommodates bare-die mounting techniques suitable for GaAs MMICs.

Part Context

This part belongs to the HMC-ALH series of low-noise amplifiers from Analog Devices. It utilizes GaAs HEMT technology to achieve high linearity and low noise in millimeter-wave frequencies. The -SX suffix typically denotes specific packaging or testing configurations for die-level components intended for custom assembly.

Replacement Considerations

The HMC-ALH140-SX serves as a related alternative within the same manufacturer's portfolio, though it covers a different frequency band (27–40 GHz) with distinct gain and noise specifications. Verify interface compatibility and performance requirements before substitution.
