HMC460

Overview

The HMC460 is a GaAs MMIC PHEMT low noise distributed amplifier die operating from DC to 20 GHz. It provides 14 dB gain, 2.5 dB noise figure, and +16 dBm output power at 1 dB gain compression. The device requires an 8 V supply with 75 mA current consumption. It features high linearity with an OIP3 of 28.5 dBm and input return loss of 12 dB. Power dissipation is rated at 2 W. Operating temperature ranges from -55°C to +85°C. This component is designed for wideband RF applications requiring high performance across the entire frequency range.

Feature Summary

• GaAs MMIC PHEMT technology for wideband operation
• Distributed amplifier architecture for flat gain response
• High linearity with elevated third-order intercept point
• Low noise figure suitable for sensitive receiver front-ends

Applications

• Wideband radar systems
• Electronic warfare receivers
• Test and measurement equipment
• Satellite communication ground stations

Procurement Notes

Verify availability status carefully as this component may be subject to limited supply or factory special order constraints. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure proper ESD protection during storage and handling. Check RoHS compliance documentation for specific regulatory needs. Validate that the bare die format matches your substrate design capabilities.

Selection Notes

Select this component when a wideband solution covering DC to 20 GHz is required. Consider the bare die format if custom packaging or direct mounting on substrates is preferred over standard surface mount packages. Evaluate thermal management needs given the 2 W power dissipation rating. Compare against packaged variants like HMC460LC5 if PCB space allows for standard SMD footprints.

Part Context

The HMC460 belongs to Analog Devices' HMC460 series of wideband distributed amplifiers. It serves as the bare die version of the packaged HMC460LC5. This family targets high-performance RF applications where broad bandwidth and consistent gain are critical. The die form factor allows integration into custom modules or hybrid circuits.
