YAT-4A+

Overview

The YAT-4A+ is a fixed-value, absorptive MMIC attenuator fabricated using Mini-Circuits' highly repetitive IPD process technology. It provides a nominal attenuation of 4 dB with a 50 Ohm impedance. The device operates over a frequency range from 0 Hz to 18 GHz and can handle up to 1.7 Watts of power. It is housed in a compact 6-VDFN package with an exposed pad for thermal management.

Feature Summary

• Absorptive design ensures high port-to-port isolation and stable performance across the operating bandwidth.
• Utilizes highly repetitive IPD process technology for consistent manufacturing quality and reliability.
• RoHS compliant construction supports environmentally conscious production standards.

Applications

• RF signal conditioning in microwave communication systems
• Attenuation stages in test and measurement equipment
• Signal level adjustment in satellite communication links

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct RoHS compliance and marking specifications. Confirm that the 6-VDFN footprint matches your PCB layout requirements. Ensure thermal design accounts for the exposed pad to maintain reliable operation at maximum power levels within the specified frequency range.

Selection Notes

Select this component when a precise 4 dB attenuation is required in broadband applications up to 18 GHz. The absorptive nature makes it suitable for environments requiring high isolation between ports. Consider the 1.7W power handling capability for moderate power applications. The surface-mount VDFN package is ideal for space-constrained designs.
