HMC-ALH364-SX

Overview

The HMC-ALH364-SX is a GaAs MMIC HEMT three-stage, self-biased Low Noise Amplifier die manufactured by Analog Devices Inc. It operates within the 24 GHz to 32 GHz frequency range. The device provides a typical gain of 21 dB with a noise figure of 2 dB. It requires a 5 V supply voltage and draws 68 mA of current. The one-dB compression point (P1dB) is 7 dBm, and input return loss is specified at 12 dB. The component is designed for surface mount installation in a die package format.

Feature Summary

• Utilizes GaAs HEMT technology for high-performance amplification
• Features a three-stage, self-biased circuit architecture
• Designed as a bare die for flexible integration

Applications

• VSAT communication systems
• DBS receiver front-ends
• W-band radar applications

Procurement Notes

Verify availability status carefully as this component may be subject to limited supply or factory special order conditions. Confirm that the die package format aligns with your assembly capabilities, as it requires specialized handling compared to standard packaged ICs. Ensure that the 5V supply requirement fits within your system power budget before finalizing procurement plans.

Selection Notes

Select this component when low noise performance is critical in the 24-32 GHz band. The 21 dB gain supports direct signal conditioning without additional amplification stages. Consider the die form factor if space constraints allow for custom mounting solutions. Verify thermal management requirements given the 68 mA operating current and potential power dissipation in enclosed environments.

Part Context

This part belongs to the HMC-ALH series of wideband low noise amplifiers from Analog Devices. These components are engineered for millimeter-wave applications requiring high linearity and minimal signal degradation. The -SX suffix typically denotes specific packaging or testing configurations within the manufacturer's product line, distinguishing it from other variants in the same functional family.
