MAADSS0019TR

Attenuators Overview

The MAADSS0019TR is a digitally controlled RF attenuator manufactured by MACOM Technology Solutions. It operates within a frequency range of 2 GHz to 6 GHz and features a 50 Ohms impedance. The device provides attenuation levels from 1 dB to 15 dB with 1 dB step resolution, utilizing 4-bit control accuracy. It is housed in a 16-VFQFN package with an exposed pad, designed for surface-mount applications requiring precise signal level management in high-frequency circuits.

Attenuators Feature Summary

• Digitally controlled attenuation with 1 dB step resolution up to 15 dB
• Operates across a wide frequency band from 2 GHz to 6 GHz
• Utilizes 4-bit control accuracy for precise signal adjustment
• Designed for surface-mount integration via 16-VFQFN exposed pad package

Attenuators Applications

• Wireless communication systems requiring variable gain control
• RF test and measurement equipment needing precise attenuation
• Base station transceivers for signal level management
• Satellite communication links requiring digital attenuation

Attenuators Procurement Notes

Verify the specific package variant, as some sources reference TSSOP-16 while official specifications indicate VFQFN. Confirm RoHS compliance and lead-free plating status with the manufacturer. Ensure the operating temperature range aligns with system requirements. Check for updated datasheets regarding electrical characteristics at higher frequencies. Validate supply chain authenticity through authorized distributors.

Attenuators Selection Notes

Select this component when digital control is required for attenuation between 1 dB and 15 dB in the 2-6 GHz range. Consider the 16-VFQFN package for compact PCB layouts. Evaluate power consumption and control logic compatibility with existing digital interfaces. Compare insertion loss and VSWR performance against system budget requirements. Ensure thermal management supports the exposed pad design.

Attenuators Part Context

This part belongs to MACOM's family of GaAs MMIC digital attenuators. It complements other models like MAATSS0019 and MAADSS0009, offering different frequency ranges and attenuation steps. The series is designed for applications demanding low power consumption and high linearity. It fits into broader RF front-end modules where digital control simplifies system architecture.

Attenuators Replacement Considerations

MAATSS0019 offers similar functionality but operates in the 0.5-4.0 GHz range. MAADSS0009 provides 30 dB attenuation with 2 dB steps up to 2 GHz. Verify frequency coverage and step resolution compatibility before substitution. Package differences may require PCB redesign. Consult MACOM for direct cross-reference recommendations.
