YAT-7A+

Overview

The YAT-7A+ is a surface-mount fixed attenuator manufactured by Mini-Circuits, designed for radio frequency applications. It provides a nominal attenuation of 7 dB with an impedance of 50 Ohms. The device operates across a frequency range from DC to 18 GHz. It features a power rating of 1.3 Watts and utilizes a 6-VDFN exposed pad package. This component is RoHS compliant and suitable for high-frequency signal processing tasks requiring precise attenuation.

Feature Summary

• Absorptive design ensures stable performance across the operational bandwidth
• Surface-mount construction facilitates automated PCB assembly processes
• Wideband operation supports frequencies extending up to 18 GHz

Applications

• RF signal level adjustment in communication systems
• Impedance matching networks in microwave circuits
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific ordering suffix against the official Mini-Circuits datasheet to ensure correct termination style and packaging configuration. Confirm that the selected variant matches the required surface-mount footprint and thermal pad specifications for your PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a 7 dB attenuation value is required within a 50 Ohm system operating up to 18 GHz. Ensure the PCB design accommodates the 6-VDFN package dimensions and exposed pad thermal requirements. Consider the 1.3 Watt power handling capability relative to the expected signal levels in the application circuit to prevent overheating or performance degradation during continuous operation.

Part Context

The YAT-7A+ belongs to the YAT-A series of fixed attenuators from Mini-Circuits. This series focuses on absorptive technology for superior isolation and return loss characteristics compared to resistive types. The component represents a standard solution for integrating precise attenuation into compact RF modules, leveraging established manufacturing processes for reliability in commercial and industrial environments.

Replacement Considerations

Consult the Mini-Circuits product selector tool for direct substitutes with identical attenuation values and frequency ranges. Verify mechanical compatibility with the existing 6-VDFN footprint if considering alternative manufacturers. Ensure any replacement maintains the 50 Ohm impedance and 1.3 Watt power rating to preserve circuit integrity without redesigning the surrounding passive network.
