HMC-ALH364

Overview

The HMC-ALH364 is a GaAs MMIC HEMT three-stage, self-biased Low Noise Amplifier die operating between 24 and 32 GHz. It provides 21 dB of gain with a noise figure of 2 dB. The amplifier delivers +7 dBm output power at 1 dB gain compression. It requires a 5 V supply voltage and draws 68 mA of current. The device features an input return loss of 12 dB and operates within a temperature range of -55°C to +85°C.

Feature Summary

• Three-stage GaAs MMIC HEMT architecture for enhanced signal amplification
• Self-biased design simplifying circuit integration requirements
• Optimized low noise performance for sensitive receiver applications

Applications

• W-band communication systems
• Point-to-point microwave links
• Satellite communication receivers

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix (e.g., SX) matches the required packaging format. Check for discontinuation notices as availability may be limited. Ensure ESD handling protocols are followed during assembly due to the bare die configuration.

Selection Notes

Select this component when W-band low noise amplification is required with minimal bias complexity. The self-biased nature reduces external passive components. Consider the bare die form factor for custom PCB integration. Verify thermal management capabilities for the specified operating temperature range.

Part Context

This part belongs to the HMC-ALH series of low noise amplifiers from Analog Devices. It utilizes Gallium Arsenide (GaAs) technology for high-frequency performance. The die package allows for flexible mounting in specialized RF modules where space constraints are critical.
