HMC448

Overview

The HMC448 is a GaAs PHEMT x2 active broadband frequency multiplier die from Analog Devices Inc. It operates with an output frequency range of 19 GHz to 25 GHz. The device requires a supply voltage between 4.5 V and 5.5 V, drawing a typical operating current of 48 mA. Maximum power dissipation is rated at 640 mW. It supports input frequencies up to 25 GHz and functions within a temperature range of -55°C to +85°C.

Feature Summary

• Utilizes GaAs PHEMT technology for high-performance RF multiplication
• Provides x2 active frequency multiplication across a broad bandwidth
• Designed as a bare die component for custom integration

Applications

• Millimeter-wave communication systems
• Local oscillator generation in radar receivers
• Test and measurement instrumentation

Procurement Notes

Verify availability status carefully as the part may be subject to limited supply or factory special orders. Confirm that the procurement channel accepts bare die components, as standard surface-mount handling procedures do not apply. Ensure compatibility with existing GaAs MMIC evaluation boards or custom carrier designs before finalizing purchase agreements.

Selection Notes

Select this component when a bare die solution is required for x2 frequency multiplication in the 19-25 GHz range. Consider the HMC448LC3BTR-R5 if a packaged SMT version is preferred over a raw die. Evaluate thermal management capabilities due to the 640 mW power dissipation rating and ensure the application circuit can support the specified 4.5 V to 5.5 V supply requirements.

Part Context

This component belongs to the HMC448G series of RF wireless miscellaneous integrated circuits manufactured by Analog Devices Inc. It falls under the sub-category of Wireless & RF Integrated Circuits. The product utilizes GaAs technology and is classified as a multiplier type device intended for specialized RF applications requiring high-frequency signal processing.

Replacement Considerations

The HMC448LC3BTR-R5 is a documented alternative offering similar functionality in a QFN-12 package.
