HMC-ALH310-SX

Overview

The HMC-ALH310-SX is a three-stage GaAs HEMT MMIC Low Noise Amplifier (LNA) operating between 37 and 42 GHz. It features 22 dB of small signal gain, 3.5 dB noise figure, and +12 dBm output power at 1dB compression from a +2.5V supply. The device draws 52mA supply current and utilizes a die package for surface mount installation.

Feature Summary

• Three-stage GaAs HEMT MMIC architecture
• High small signal gain of 22 dB
• Low noise figure of 3.5 dB
• +12 dBm output power at 1dB compression

Applications

• Ka-band communication systems
• Satellite ground station receivers
• Point-to-point microwave links

Procurement Notes

Verify the specific suffix '-SX' against official Analog Devices documentation to confirm it denotes the bare die configuration rather than a packaged variant. Ensure compatibility with existing RF layout designs requiring exposed die mounting. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors prior to final procurement decisions.

Selection Notes

Select this component for applications requiring high gain and low noise in the 37-42 GHz range. Consider the +2.5V supply requirement and 52mA current draw during power budgeting. Evaluate thermal management needs for the bare die format. Compare performance metrics against alternative LNAs if system constraints differ significantly.
