MAAD-007081-000100

Overview

The MAAD-007081-000100 is a GaAs FET-based 5-bit digital attenuator manufactured by MACOM Technology Solutions. It features an integral TTL driver for simplified control interface integration. The device provides a total attenuation range of 15.5 dB with a step size of 0.5 dB. It operates within a frequency range of 0 Hz to 3.5 GHz and maintains a system impedance of 50 Ohms. The component is housed in a 32-PowerVFQFN package, designed for surface-mount applications requiring precise RF signal level adjustment.

Feature Summary

• Integrates a GaAs FET switching structure with a dedicated TTL driver circuit for direct logic control
• Provides 5-bit resolution allowing for fine-grained attenuation steps across the operational bandwidth
• Designed for high-frequency operation up to 3.5 GHz with standard 50 Ohm impedance matching

Applications

• RF signal path gain control in communication systems
• Attenuation stages in test and measurement equipment
• Beamforming networks requiring variable phase and amplitude control

Procurement Notes

Verify the specific ordering suffix and package variant against the official MACOM datasheet prior to purchase. Confirm that the supply source provides valid traceability documentation. Ensure compatibility with the intended PCB footprint and thermal management requirements for the 32-PowerVFQFN package. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a compact, monolithic solution for 5-bit digital attenuation is required up to 3.5 GHz. The integral TTL driver eliminates the need for external control logic, simplifying board layout. Consider the 32-PowerVFQFN package constraints regarding thermal dissipation and soldering profiles during design integration.
