MAAD-009170-0001TR

Overview

The MAAD-009170-0001TR is a GaAs pHEMT 5-bit digital attenuator manufactured by MACOM Technology Solutions. It features an integral TTL driver and operates within a frequency range of 0 Hz to 4 GHz. The device provides an attenuation range of 0.5 dB to 15.5 dB with 50 Ohms impedance. It is housed in a 32-PowerVFQFN surface mount package, designed for minimal phase variation over the attenuation range.

Feature Summary

• Integrates TTL driver circuitry for simplified control interface
• Utilizes GaAs pHEMT technology for high-performance signal attenuation
• Maintains minimal phase variation across the entire attenuation range

Applications

• RF test and measurement equipment requiring precise signal level adjustment
• Wireless communication systems needing variable gain control
• Military and aerospace radar systems demanding stable phase characteristics

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm the 32-PowerVFQFN package dimensions match your PCB layout requirements. Ensure the integral TTL driver voltage levels align with your system logic. Check current availability status as supply may be restricted. Validate that the 0-4 GHz frequency range meets your application needs.

Selection Notes

Select this component when a compact, monolithic solution for digital attenuation is required. The integrated driver eliminates external logic components, reducing board space. Consider the 5-bit resolution for applications needing fine attenuation steps. Evaluate the PowerVFQFN package for thermal management capabilities in dense layouts.
