MAAD-011055-DIE

Overview

The MAAD-011055-DIE is a broadband bidirectional digital step attenuator manufactured by MACOM Technology Solutions. It utilizes GaAs pHEMT technology to provide a fixed 6 dB attenuation step size. The device operates as a 1-bit attenuator with a frequency range extending from DC to 30 GHz. It features complementary logic inputs requiring 0 V and -5 V signals for control. The component is designed for high-performance RF applications requiring precise signal level adjustment across a wide bandwidth.

Feature Summary

• Broadband operation covering DC to 30 GHz
• Bidirectional signal transmission capability
• GaAs pHEMT technology construction
• Complementary 0 V and -5 V logic input control

Applications

• RF test and measurement equipment
• Wireless communication systems
• Satellite communication links
• Broadband CATV infrastructure

Procurement Notes

Verify the specific die configuration against the official datasheet before integration, as the suffix indicates a bare die format rather than a packaged component. Confirm that the manufacturing lead time aligns with project schedules, as standard lead times may extend to approximately 18 weeks depending on current production capacity. Ensure that the supply chain source provides valid traceability documentation for the semiconductor material.

Selection Notes

Select this component when a single-stage 6 dB attenuation is required within a multi-bit attenuator array or standalone application. The 30 GHz upper limit supports high-frequency microwave designs where standard silicon devices fail. Consider the complementary voltage requirement for interface compatibility with existing control circuitry. Evaluate the bidirectional nature if signal flow direction varies during system operation.

Part Context

This part belongs to the MAAD series of digital step attenuators from MACOM. It complements other bits in a stackable architecture to form higher-resolution attenuators. The die format allows for custom packaging solutions tailored to specific thermal or mechanical constraints. It serves as a fundamental building block for precision RF signal conditioning networks.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Equivalent performance may require evaluating other MACOM 1-bit 6 dB attenuators such as the MAAD-011055 in alternative packages. Verify pinout and electrical specifications carefully when cross-referencing with similar models from different manufacturers.
