HMC395

Overview

The HMC395 is a GaAs InGaP Heterojunction Bi-polar Transistor (HBT) Gain Block MMIC amplifier die designed for operation from DC to 4 GHz. It operates on a 5 V supply with a current draw of 54 mA. Key electrical specifications include a gain of 15 dB, a noise figure of 4.5 dB, an output P1dB of 15 dBm, and an OIP3 of 28 dBm. The component supports an operating temperature range from -55°C to +85°C.

Feature Summary

• Utilizes InGaP HBT technology for high-performance amplification
• Provides wideband coverage from DC to 4 GHz
• Engineered as a bare die for integration into custom RF modules

Applications

• VSAT systems
• Wireless infrastructure components
• General-purpose RF gain stages

Procurement Notes

Verify the obsolete lifecycle status before design finalization. Confirm that the bare die format meets your assembly capabilities, as standard packaging is not available. Source only through authorized distributors or secondary market suppliers due to discontinuation. Validate technical compatibility with existing system requirements prior to acquisition.

Selection Notes

Select this component when a wideband DC-4 GHz gain block is required in a compact form factor. Consider the specific thermal management needs for the -55°C to +85°C range. Evaluate the 15 dB gain and 4.5 dB noise figure against system link budget requirements. Ensure the bare die package type aligns with the target PCB design constraints.

Part Context

The HMC395 belongs to Analog Devices' portfolio of monolithic microwave integrated circuits (MMICs). It serves as a fundamental building block for radio frequency signal chains. As a gain block, it amplifies signals without significant distortion within its specified bandwidth. The device represents a mature technology solution for legacy and specialized RF applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative solutions require independent engineering validation to ensure equivalent performance characteristics.
