MAATCC0009TR

Overview

The MAATCC0009TR is a digitally controlled RF attenuator manufactured by MACOM Technology Solutions. It operates within a frequency range of 0 Hz to 4 GHz and provides an attenuation range from 0.5 dB to 31.5 dB in 0.5 dB steps. The device features a 6-bit resolution and utilizes a TTL driver interface for control. It has a nominal impedance of 50 ohms and is housed in a 32-PowerVFQFN package. Key electrical specifications include a maximum VSWR of 2.2 and a typical insertion loss of 5.1 dB. The component supports operation temperatures between -40°C and +85°C.

Feature Summary

• Digital control via TTL interface for precise attenuation adjustment
• Wideband operation covering DC to 4 GHz frequencies
• High-resolution 6-bit step control with 0.5 dB increments
• Integrated driver circuitry simplifies system integration

Applications

• RF signal path gain control in communication systems
• Test and measurement equipment requiring variable attenuation
• Phased array antenna beamforming networks
• Wireless infrastructure base station modules

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm the TTL logic level compatibility with your system's control voltage requirements. Ensure the 32-PowerVFQFN thermal pad soldering process meets PCB assembly standards for reliable thermal dissipation during operation.

Selection Notes

Select this component for applications requiring digital control over analog voltage inputs. Consider the 5.1 dB insertion loss impact on overall system noise figure. Evaluate the 32-pin QFN footprint against available PCB real estate constraints. Compare performance metrics against alternative attenuators if higher frequency or lower loss is required.

Part Context

This part belongs to MACOM's family of digitally controlled attenuators designed for RF and microwave applications. It integrates the attenuator core and driver electronics into a single compact surface-mount package. The series offers various attenuation ranges and pin configurations to suit different design needs while maintaining consistent performance characteristics across the product line.

Replacement Considerations

Consult official MACOM documentation for direct cross-reference substitutes. Verify pinout compatibility and thermal resistance values before substituting. Ensure replacement parts meet the same 0-4 GHz frequency and 50-ohm impedance specifications.
