MAATCC0009

Overview

The MAATCC0009 is a GaAs FET-based digital attenuator manufactured by MACOM Technology Solutions. It features an integral TTL driver and operates within a frequency range of DC to 4 GHz. The device provides a total attenuation range of 31.5 dB with a step size of 0.5 dB, controlled via a 6-bit interface. It maintains a 50-ohm impedance and is housed in a 32-PowerVFQFN package. Key electrical specifications include a maximum VSWR of 2.2 and an insertion loss of 5.1 dB. The component supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates a TTL driver for direct logic control compatibility
• Utilizes GaAs FET technology for high-frequency performance
• Provides precise 0.5 dB step resolution across the attenuation range

Applications

• RF signal path attenuation control
• Test and measurement equipment
• Wireless communication systems

Procurement Notes

Verify the specific ordering suffix when purchasing, as variants such as MAATCC0009TR indicate tape-and-reel packaging while the base part number may imply bulk supply. Confirm RoHS compliance status and ensure the selected package matches the PCB footprint requirements. Cross-reference the datasheet revision date to guarantee access to the most current electrical characteristics and mechanical drawings before finalizing procurement orders.

Selection Notes

Select this component when a wide bandwidth up to 4 GHz is required alongside fine 0.5 dB resolution steps. The integrated TTL driver simplifies interface design compared to devices requiring external drivers. Ensure the application environment stays within the specified -40°C to +85°C temperature range. Consider the 32-PowerVFQFN package dimensions for thermal management and board space constraints relative to alternative SOIC packages.

Part Context

This device belongs to MACOM's family of digital attenuators designed for RF applications. Unlike the MAATCC0007 which covers DC to 2 GHz, or the MAATCC0008 offering 15 dB range, the MAATCC0009 extends the frequency capability to 4 GHz with higher resolution. It serves as a specialized solution for systems demanding precise gain control over broad bandwidths using standard logic interfaces.
