HMC441-SX

Overview

The HMC441-SX is a GaAs pHEMT MMIC medium power amplifier from Analog Devices Inc., designed for operation in the 6 GHz to 18 GHz frequency range. This die-level component provides a typical small-signal gain of 14.5 dB and a 1 dB compression point (P1dB) of 20 dBm. It features a low noise figure, ensuring high signal integrity across its wide bandwidth. The device is optimized for applications requiring robust RF performance in a compact form factor.

Feature Summary

• Utilizes GaAs pHEMT technology for high-performance RF amplification
• Provides medium power output with significant gain across a wide microwave band
• Engineered for low noise figure to maintain signal quality
• Supplied as an exposed die for flexible integration into custom substrates

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Electronic warfare systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix requirements when ordering, as the -SX designation indicates a bare die configuration distinct from packaged variants. Confirm that your assembly process supports direct die attachment and wire bonding, as this component lacks a standard surface-mount package. Ensure compatibility with your substrate materials and thermal management strategies before procurement.

Selection Notes

Select the HMC441-SX when a wideband 6-18 GHz medium power amplifier is required in a minimal footprint. Consider this die option if your design utilizes custom PCBs or hybrid circuits rather than standard SMD packages. Evaluate the need for external matching networks and biasing circuits, as the die requires peripheral components for optimal operation within your specific system architecture.

Part Context

This component belongs to the HMC441 family of medium power amplifiers manufactured by Analog Devices Inc. The -SX suffix specifically denotes the exposed die version, differentiating it from packaged equivalents like the HMC441LC3B. It shares core electrical characteristics with the series but offers distinct mechanical integration options for advanced RF module designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices technical support for qualified alternatives or verify compatibility with other HMC series amplifiers based on specific frequency and power requirements.
