MAATCC0006

Overview

The MAATCC0006 is a GaAs FET digital attenuator manufactured by MACOM Technology Solutions. It provides a total attenuation range of 30 dB with a minimum step size of 2.0 dB, controlled via TTL-compatible logic inputs. The device operates over a frequency range from DC to 3 GHz and maintains a 50 Ohm impedance. Key electrical specifications include a maximum VSWR of 1.7 and an insertion loss of 3.1 dB. It supports a power rating of 34 dBm and functions within a temperature range of -40°C to +85°C. The component is housed in a 16-SOIC surface-mount package.

Feature Summary

• Utilizes GaAs FET technology for reliable RF signal attenuation
• Features 4-bit digital control with TTL driver compatibility
• Provides precise 2.0 dB step resolution across the attenuation range
• Designed as a lead-free equivalent to legacy AT65-02 components

Applications

• RF signal path management in wireless communication systems
• Test and measurement equipment requiring variable attenuation
• Base station front-end modules
• Satellite communication receivers

Procurement Notes

Verify that the specific order quantity meets the manufacturer's factory packaging requirements, which may involve minimum order quantities or reel sizes. Confirm RoHS3 compliance status if environmental regulations are critical. Ensure the procurement channel sources genuine MACOM products to guarantee performance specifications and reliability standards are met.

Selection Notes

Select this component when a 30 dB attenuation range with 2.0 dB steps is required up to 3 GHz. It is suitable for applications needing TTL-compatible digital control and low VSWR. Consider the SOIC-16 package for surface-mount assembly constraints. Verify that the 34 dBm power handling and operating temperature range align with system design parameters.

Part Context

This part belongs to MACOM's family of digitally controlled attenuators designed for RF and microwave applications. It serves as a modern, lead-free replacement for older discrete or hybrid attenuator solutions. The integration of GaAs FET technology allows for compact form factors while maintaining high linearity and stability in demanding RF environments.

Replacement Considerations

The MAATCC0006 is explicitly documented as a Pb-Free equivalent of the AT65-02. When substituting, verify pinout compatibility and ensure the legacy component's specifications do not exceed the MAATCC0006's limits regarding frequency, power, or control voltage levels.
