MAATCC0005

Overview

The MAATCC0005 is a GaAs FET digital attenuator manufactured by MACOM Technology Solutions. It provides a total attenuation range of 31.5 dB with a minimum step size of 0.5 dB, controlled via TTL-compatible logic inputs. The device operates over a frequency range from DC to 2 GHz and maintains a 50 Ohm impedance. Packaged in a lead-free 24-SOIC surface-mount case, it features an insertion loss of 4.2 dB and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes GaAs FET technology for high-performance RF signal control
• Offers precise digital attenuation control with 0.5 dB minimum step resolution
• Compatible with standard TTL driver logic interfaces

Applications

• Wireless communication base stations
• Test and measurement instrumentation
• Military radar systems

Procurement Notes

Verify the specific package variant during procurement, as documentation references both 20-lead and 24-lead SOIC configurations for this series. Confirm RoHS compliance status and ensure the ordering suffix matches the required pinout and thermal characteristics. Cross-reference the manufacturer datasheet to validate the exact electrical specifications against your system requirements before finalizing the purchase order.

Selection Notes

Select the MAATCC0005 when a wide bandwidth up to 2 GHz is required alongside fine 0.5 dB attenuation steps. This component is suitable for applications demanding low insertion loss and high linearity. Ensure the design accommodates the 24-SOIC footprint and that the driving circuitry provides compatible TTL voltage levels for reliable digital control of the attenuation state.

Part Context

This part belongs to MACOM's MMIC digital attenuator family, designed for broadband RF applications. It serves as a direct replacement or equivalent for legacy components like the AT65-04. The device integrates multiple attenuation stages into a single compact chip, simplifying board layout compared to discrete solutions while maintaining consistent performance across the specified frequency band.

Replacement Considerations

The MAATCC0005 is documented as an equivalent to the AT65-04. Verify pin compatibility and electrical tolerances when substituting other models in the MAATCC series.
