MAATCC0007

Overview

The MAATCC0007 is a GaAs FET digital attenuator manufactured by MACOM Technology Solutions. It provides a total attenuation range of 31 dB with a step size of 1.0 dB, controlled via an integral TTL driver. The device operates within a frequency range of DC to 2 GHz and maintains a system impedance of 50 Ohms. It is housed in a 16-SOIC package measuring 0.295 inches (7.50 mm) in width. The component is RoHS3 compliant and classified under EAR99 export regulations.

Feature Summary

• Integrates a TTL driver for direct logic control
• Utilizes GaAs FET technology for RF signal attenuation
• Provides precise 1.0 dB step resolution

Applications

• RF signal path control systems
• Test and measurement instrumentation
• Telecommunications equipment

Procurement Notes

Verify the specific package variant against the official datasheet to ensure compatibility with PCB footprint requirements. Confirm that the operating environment remains within the specified temperature range and voltage limits defined in the electrical characteristics section. Ensure supply chain sources provide documentation confirming RoHS3 compliance status prior to final procurement authorization.

Selection Notes

Select this component when a fixed 31 dB attenuation profile is required for DC to 2 GHz applications. The integrated TTL interface simplifies control circuitry design compared to analog alternatives. Evaluate thermal management needs based on the SOIC package constraints and ensure the driving logic levels match the specified TTL input requirements for reliable operation.

Part Context

This part belongs to the MAATCC series of digital attenuators from MACOM. These devices are designed for high-reliability RF applications requiring precise attenuation control. The series typically utilizes GaAs technology to achieve performance across microwave frequencies while maintaining compact form factors suitable for modern electronic assemblies.

Replacement Considerations

The MAATCC0008 offers 15 dB attenuation up to 3 GHz, while the MAATCC0009 provides 31.5 dB attenuation up to 4 GHz. Both alternatives differ in attenuation values, maximum frequency capabilities, and physical packaging, requiring schematic and layout modifications if substituted.
