HMC-ALH376-SX

Overview

The HMC-ALH376-SX is a GaAs MMIC HEMT low-noise amplifier from Analog Devices Inc., designed for the W-band frequency range of 35 GHz to 45 GHz. It features a three-stage, self-biased architecture implemented in a bare die package suitable for surface mount applications. The device provides a typical gain of 12 dB and a noise figure of 2.2 dB. It operates with a supply voltage of 4 V and draws a current of 87 mA. The output power at 1 dB gain compression (P1dB) is specified at 6 dBm.

Feature Summary

• Utilizes GaAs HEMT technology for high-frequency performance
• Features a self-biased three-stage amplifier design
• Optimized for low noise figure in the W-band spectrum

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the received unit matches the specific HMC-ALH376-SX designation, as availability may be restricted. Ensure handling procedures account for the bare die format to prevent electrostatic discharge damage during installation.

Selection Notes

Select this component when designing circuits requiring amplification within the 35-45 GHz range. Consider the 4 V supply requirement and 87 mA current draw for power budgeting. Evaluate the bare die form factor against available PCB space and mounting capabilities, ensuring thermal management strategies align with the device's power dissipation characteristics.

Part Context

This part belongs to the HMC-ALH series of wideband low-noise amplifiers manufactured by Analog Devices Inc. The -SX suffix typically denotes a specific packaging or testing configuration variant within the broader product family, distinguishing it from standard tape-and-reel or other package options.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference specifications such as operating frequency, gain, and noise figure to ensure functional compatibility before substituting.
