HMC576-SX

Overview

The HMC576-SX is a GaAs MMIC active frequency multiplier manufactured by Analog Devices Inc. It operates within an output frequency range of 18 GHz to 29 GHz, utilizing a x2 multiplication factor. The device is supplied in a bare die package format, specifically designated as the SX suffix variant. It requires a DC supply voltage between 4.5 V and 5.5 V, with a typical operating current of 82 mA. The component supports an extended industrial temperature range from -55°C to +85°C and exhibits a power dissipation rating of 709 mW.

Feature Summary

• Integrates active frequency multiplication circuitry on a single GaAs MMIC die for compact integration
• Provides wideband operation across the 18 GHz to 29 GHz output spectrum
• Designed for surface-mount attachment via wire bonding or flip-chip processes

Applications

• Radar systems requiring high-frequency signal generation
• VSAT communication uplink chains
• Point-to-point microwave radio links

Procurement Notes

Verify that the procurement channel supplies the specific 'SX' suffix variant, which denotes the bare die configuration distinct from packaged versions like the LC3B. Confirm compatibility with the required gel pack handling procedures for exposed dies. Ensure the source documentation explicitly lists the 18-29 GHz output range and 82 mA current consumption to avoid confusion with other family members. Request the official datasheet to validate the specific pinout and thermal pad requirements for the die form factor prior to finalizing the order.

Selection Notes

Select this component when a bare die solution is preferred over packaged ICs to minimize parasitic effects and board space in high-frequency designs. The HMC576-SX is suitable for applications demanding a x2 multiplication ratio within the Ka-band spectrum. Consider the GaAs technology for its performance characteristics at these frequencies. Evaluate the system's ability to handle the 709 mW power dissipation and the specific thermal management needs associated with bare die mounting compared to standard QFN packages.

Part Context

This part belongs to the HMC576G series of RF wireless miscellaneous components produced by Analog Devices Inc. It is categorized under Wireless & RF Integrated Circuits, specifically as an active multiplier. The product utilizes Gallium Arsenide (GaAs) technology. The 'SX' designation identifies it as the die version, differentiating it from the SMT packaged HMC576LC3B variant while sharing the same core functional specifications.
