MAAD-011057-DIE

Overview

The MAAD-011057-DIE is a broadband bidirectional 1-bit GaAs pHEMT digital step attenuator with a fixed 10 dB attenuation step size. It operates from DC to 30 GHz and features complementary 0 V and -5 V logic inputs for control. The device is designed as a die-level component, requiring integration into custom substrates or packages. It provides precise attenuation control in high-frequency applications without the need for complex biasing networks.

Feature Summary

• Broadband operation covering DC to 30 GHz
• Bidirectional signal path capability
• Simple complementary logic input control

Applications

• High-frequency test and measurement equipment
• Phased array radar systems
• Satellite communication ground stations

Procurement Notes

Verify that the procurement source explicitly supplies bare die components suitable for direct mounting. Confirm substrate compatibility and handling requirements for fragile semiconductor dies. Ensure the supplier provides traceability documentation consistent with MACOM's manufacturing standards for unencapsulated RF components.

Selection Notes

Select this component when a compact, high-speed digital attenuation solution is required up to 30 GHz. Consider the need for custom packaging or substrate design since it is a die-only part. Evaluate thermal management strategies appropriate for bare die operation in high-power RF environments.

Part Context

This component belongs to MACOM's MAAD series of digital step attenuators. It utilizes GaAs pHEMT technology to achieve wide bandwidth and fast switching speeds. The die format allows system designers to integrate attenuation directly into multi-chip modules or hybrid circuits.
