MAAD-011045-TR0500

Overview

The MAAD-011045-TR0500 is a wideband digital step attenuator from MACOM Technology Solutions, operating across a frequency range of 0 Hz to 18 GHz. This component provides an attenuation value ranging from 0.5 dB to 31.5 dB with a least significant bit (LSB) step of 0.5 dB. It is housed in a lead-free 3mm 20-lead surface mount plastic package with an exposed pad for thermal management. The device features consistent phase characteristics and is designed for high reliability in RF applications.

Feature Summary

• Wideband operation covering DC to 18 GHz
• 6-bit resolution with 0.5 dB LSB step size
• Lead-free 3mm 20-lead surface mount package
• Consistent phase response across the frequency range

Applications

• Wireless communication systems
• Test and measurement equipment
• Military and aerospace radar systems
• Satellite communication links

Procurement Notes

Verify the specific suffix TR0500 indicates the tape and reel packaging configuration with a quantity of 500 units per reel. Confirm moisture sensitivity level requirements for storage and handling prior to assembly. Ensure the 3mm 20-lead footprint matches the target PCB design. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when a wide bandwidth up to 18 GHz is required with fine 0.5 dB control steps. The 6-bit resolution offers 64 distinct attenuation states suitable for precise signal level adjustment. Consider the 3mm 20-lead package for compact board space constraints. Evaluate thermal performance needs due to the exposed pad design for heat dissipation.
