YAT-2A+

Overview

The YAT-2A+ is a fixed value, absorptive MMIC attenuator fabricated using highly repetitive IPD process technology. It provides a fixed attenuation of 2dB across a wide frequency range from 0 Hz to 18 GHz. The component features a maximum operating temperature of +85 C and handles up to 2W of power. It operates at an impedance of 50 Ohms with a maximum VSWR of 1.9. The device is housed in a miniature MCLP package measuring 2 x 2 mm.

Feature Summary

• Exceptional power handling capability for robust RF applications
• Wide bandwidth coverage extending from DC to 18 GHz
• Miniature surface mount package for space-constrained designs
• Excellent attenuation accuracy and flatness

Applications

• RF and microwave signal conditioning
• Satellite communications systems
• Automotive radar applications
• Quantum computing infrastructure

Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS standards and confirm the package type matches the design requirements. Check the manufacturer's datasheet for detailed mechanical drawings and soldering recommendations. Ensure the selected variant meets the required power handling and frequency specifications for the intended application environment.

Selection Notes

Select this component when a fixed 2dB attenuation is required across a broad spectrum up to 18 GHz. Consider the 2W power handling capacity for high-power signal paths. The small MCLP footprint makes it suitable for dense PCB layouts. Verify that the 50 Ohm impedance aligns with the system architecture.

Part Context

Mini-Circuits is a global leader in the design and manufacturing of RF, IF, and microwave components from DC to 86GHz. The YAT-2A+ belongs to their line of fixed attenuators, utilizing advanced IPD process technology to deliver reliable performance in demanding environments.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the YAT series. Verify that any alternative maintains the same 2dB attenuation value, 18 GHz frequency limit, and 50 Ohm impedance. Ensure the replacement package size fits the existing board layout.
