MAATSS0021TR-3000

Overview

The MAATSS0021TR-3000 is a GaAs MMIC digital attenuator manufactured by MACOM Technology Solutions. It features a 5-bit control structure with a 0.5 dB step size, providing an attenuation range of 0.5 dB to 15.5 dB. The device operates within a frequency range of 0 Hz to 2 GHz and maintains a 50 Ohm impedance. Packaged in a lead-free 16-SOIC surface mount plastic package, it supports precise signal level adjustment for RF applications.

Feature Summary

• Integrates 5-bit digital control for programmable attenuation steps
• Utilizes GaAs MMIC technology for low-noise performance
• Designed for surface mount assembly in a 16-SOIC package

Applications

• RF signal conditioning circuits
• Sensor signal processing systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific ordering suffix against official MACOM documentation to ensure correct packaging configuration. Confirm that the 16-SOIC package variant matches the required board layout. Check RoHS compliance status and moisture sensitivity levels prior to integration into production assemblies.

Selection Notes

Select this component when a compact, digitally controlled attenuation solution is required for frequencies up to 2 GHz. The 0.5 dB step resolution suits applications demanding fine-grained signal adjustment. Ensure the 16-SOIC footprint aligns with existing PCB designs and thermal management requirements.

Part Context

This part belongs to MACOM's portfolio of GaAs MMIC digital attenuators. It provides a cost-effective alternative to variable gain amplifiers or analog attenuators where discrete digital control is preferred. The SOIC-16 package facilitates automated assembly processes common in consumer electronics manufacturing.

Replacement Considerations

Consult MACOM's official substitution guide for verified equivalents. Generic replacements may not match the 0.5 dB step accuracy or GaAs material properties. Verify pinout compatibility before swapping with other 16-pin attenuator families.
