HMC642-SX

Overview

The HMC642-SX is a GaAs MMIC 6-bit digital phase shifter designed for the 9 GHz to 12.5 GHz frequency range. It provides 360 degrees of total phase coverage with a least significant bit (LSB) resolution of 5.625 degrees. The device exhibits low RMS phase error, typically between 2.5 and 3.5 degrees across all phase states, and maintains an insertion loss of approximately 0.25 dB. Packaged as a bare die, it operates on a single supply voltage ranging from 0 V to 5 V.

Feature Summary

• Six-bit digital control architecture enabling precise phase adjustment
• GaAs MMIC technology optimized for high-frequency RF applications
• Low RMS phase error ensuring signal integrity across the operating band

Applications

• Phased array antenna systems
• Radar beam steering modules
• Microwave communication links

Procurement Notes

Verify the specific suffix and revision level against the official Analog Devices datasheet before procurement. Confirm that the bare die form factor aligns with your assembly capabilities, as standard packaging is not applicable. Ensure supply chain channels are authorized to prevent counterfeit components.

Selection Notes

Select this component when a wideband digital phase shift is required within the Ku-band spectrum. Consider the bare die package constraints and thermal management requirements during PCB layout. Evaluate the need for external matching networks if the integrated impedance does not match the system design.

Part Context

This part belongs to the HMC642 family of digital phase shifters from Analog Devices. It utilizes Gallium Arsenide (GaAs) monolithic microwave integrated circuit technology. The -SX suffix indicates the bare die configuration, distinguishing it from packaged variants like the HMC642ALC5TR.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for qualified alternatives or newer generation replacements.
