MAAD-011021-0GPDIE

Overview

The MAAD-011021-0GPDIE is a bare die, wideband 6-bit digital attenuator from MACOM Technology Solutions. It operates from DC to 40 GHz with a 50 Ohm impedance. The device provides up to 31.5 dB of attenuation in 0.5 dB steps. Attenuation error is typically less than ± 0.5 dB, and RMS phase error is less than 5° at 20 GHz.

Feature Summary

• Provides precise digital control over signal attenuation levels across a wide frequency range.
• Offers high linearity and low insertion loss characteristics suitable for demanding RF applications.
• Features compact bare die packaging for integration into custom microwave modules.

Applications

• Phased array antenna systems
• Test and measurement equipment
• Wireless infrastructure components

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the base model MAAD-011021 is available in both PQFN packages and bare die formats. Ensure that the selected variant matches the required frequency extension, noting that the bare die version supports operation up to 40 GHz while packaged versions may be rated for lower frequencies. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when wideband coverage extending to 40 GHz is required for digital attenuation control. The bare die format is appropriate for custom substrate integration where space constraints are critical. Evaluate the typical attenuation error and phase error specifications against system requirements to ensure signal integrity is maintained across the entire operating bandwidth.

Part Context

This part belongs to the MAAD series of digital attenuators from MACOM. It complements other RF components such as the MASW-011021 SPDT switch and MAMX mixer series, providing essential signal level control within broader RF front-end architectures designed for high-frequency wireless communications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative manufacturers or different bit-resolution attenuators from the same product family.
