MAATCC0008

Overview

The MAATCC0008 is a GaAs FET-based digital attenuator manufactured by MACOM Technology Solutions. It provides a total attenuation range of 15 dB with a minimum step size of 1 dB, controlled via TTL logic inputs. The device operates over a frequency range from 0 Hz to 3 GHz and maintains a 50-ohm impedance. Key electrical specifications include a maximum insertion loss of 2.6 dB and a maximum VSWR of 1.6. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes GaAs FET technology for reliable RF signal control
• Features TTL-compatible digital control interface
• Provides precise 1 dB step resolution across the attenuation range

Applications

• RF test and measurement equipment
• Wireless communication systems
• Military and aerospace radar subsystems

Procurement Notes

Verify the specific ordering suffix against the official MACOM datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the required tolerance and driver voltage levels match the system design requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact, digitally controlled attenuator is needed for frequencies up to 3 GHz. The 16-SOIC package facilitates surface-mount assembly, while the 15 dB range suits applications requiring moderate signal adjustment without excessive complexity.

Part Context

This part belongs to MACOM's MAATCC series of monolithic microwave integrated circuit (MMIC) digital attenuators. These devices are designed for high-reliability applications requiring precise gain control in RF signal paths, offering a balance between performance and integration density.

Replacement Considerations

The MAATCC0008 is noted as a lead-free equivalent to the AT65-04. Verify pinout compatibility and thermal characteristics when substituting other discrete or MMIC attenuators in existing designs.
