HMC464

Overview

The HMC464 is a GaAs PHEMT MMIC distributed power amplifier die designed for operation across the 2 GHz to 20 GHz frequency range. It delivers a typical gain of 16 dB and an output IP3 of +30 dBm. The device achieves a saturated output power of +26 dBm at 1 dB gain compression. It requires a supply voltage between 7.5 V and 8.5 V. This component is intended for integration into custom RF systems requiring wideband amplification.

Feature Summary

• Utilizes GaAs PHEMT technology for high-performance microwave amplification
• Provides wideband coverage from 2 GHz to 20 GHz
• Features distributed architecture for consistent gain across the spectrum

Applications

• Test instrumentation systems
• Wideband communication links
• Military radar subsystems

Procurement Notes

Verify that the specific procurement channel supplies the bare die variant, as packaging differs from packaged ICs. Confirm compatibility with your substrate and interconnect design for the exposed die format. Ensure thermal management strategies account for the power dissipation characteristics defined in the official datasheet. Validate that the supply voltage requirements align with your system's power rails before integration.

Selection Notes

Select this component when a wideband solution covering up to 20 GHz is required without the need for discrete matching networks. Consider the bare die form factor if space constraints or custom PCB integration are priorities. Evaluate the 16 dB gain and +30 dBm IP3 against system linearity and noise requirements. Ensure the designer has experience handling unpackaged semiconductor dies for proper mounting and wire bonding.

Part Context

This part belongs to Analog Devices' HMC series of monolithic microwave integrated circuits (MMICs). It serves as a wideband power amplifier option within their portfolio, distinct from lower-frequency or narrowband variants. The HMC464 complements other components like the HMC442 by offering broader bandwidth coverage rather than higher frequency operation.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires verifying electrical equivalence and mechanical compatibility with the original design specifications.
