HMC-ALH140-SX

Overview

The HMC-ALH140-SX is a GaAs HEMT W-band low noise amplifier from Analog Devices Inc., operating within the 27 GHz to 40 GHz frequency range. It delivers a gain of 11.5 dB with a noise figure of 4 dB. The device requires a 4 V supply voltage and draws 60 mA of current. Key performance metrics include a P1dB compression point of 15 dBm. Packaged as a die for surface-mount installation, it supports operation down to -55°C.

Feature Summary

• Utilizes GaAs HEMT technology for high-frequency W-band amplification
• Provides stable low-noise signal processing in the 27-40 GHz spectrum
• Engineered for compact integration via bare die packaging

Applications

• VSAT communication systems
• DBS satellite broadcasting receivers
• Point-to-point microwave links
• W-band radar subsystems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm specific die handling requirements and electrostatic discharge protection protocols during storage and assembly. Ensure supply chain documentation matches official manufacturer specifications for quality assurance and compliance verification.

Selection Notes

Select this component for applications requiring high gain and moderate noise figures in the W-band spectrum. Evaluate thermal management strategies suitable for bare die implementations. Compare against alternative models like HMC-ALH445 if lower frequency ranges or different power consumption profiles are required for the specific system design constraints.
