MAAD-011036-TR0500

Overview

The MAAD-011036-TR0500 is a wideband 6-bit digital step attenuator MMIC from MACOM Technology Solutions. It operates across a frequency range of 0.1 GHz to 30 GHz with a resolution of 0.5 dB per step, providing a total attenuation range of 0.5 dB to 31.5 dB. The device features serial or parallel control interfaces and is housed in a lead-free 4 mm x 4 mm 24-lead PQFN surface-mount package with an exposed pad. It utilizes GaAs pHEMT technology for high performance.

Feature Summary

• Wideband operation covering 0.1 GHz to 30 GHz
• 6-bit resolution with 0.5 dB step size
• Supports both serial and parallel control modes
• Lead-free 24-lead PQFN surface mount package

Applications

• High-frequency test and measurement equipment
• Wireless infrastructure systems
• Phased array radar systems
• Satellite communication terminals

Procurement Notes

Verify the specific ordering suffix TR0500 confirms the tape and reel packaging quantity as documented by the manufacturer. Ensure compatibility with the 24-VFQFN exposed pad footprint during PCB layout. Confirm that the control logic levels match the system interface requirements for serial or parallel operation. Check RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a wide bandwidth up to 30 GHz is required with precise 0.5 dB attenuation steps. The 6-bit resolution offers a balance between control complexity and attenuation granularity. Consider the PQFN package for compact designs requiring thermal dissipation through the exposed pad. Evaluate control interface needs to determine between serial or parallel configuration options.

Part Context

This part belongs to MACOM's MAAD series of digital step attenuators. It is designed for applications requiring programmable attenuation in microwave and millimeter-wave frequencies. The device integrates control logic and attenuation cells into a single MMIC die, simplifying system design compared to discrete solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative manufacturers' components for the 0.1-30 GHz range.
