YAT-5A+

Overview

The YAT-5A+ is a fixed attenuator manufactured by Mini-Circuits, designed for RF and microwave applications. It provides a nominal attenuation of 5 dB across a frequency range from DC to 18 GHz. The component operates with a characteristic impedance of 50 Ohms and can handle a maximum power rating of 1.4 Watts. Typical performance data indicates an attenuation value of approximately 4.89 dB at frequencies up to 200 MHz, with a Voltage Standing Wave Ratio (VSWR) remaining below 1.15 in this range. The device is housed in a compact surface-mount package.

Feature Summary

• Provides fixed 5 dB attenuation across a wide frequency spectrum extending to 18 GHz
• Designed for high-power handling capabilities up to 1.4 Watts
• Maintains low VSWR for efficient signal transmission in RF systems

Applications

• RF signal level control in communication systems
• Microwave circuit testing and measurement setups
• Impedance matching in high-frequency electronic designs

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters such as attenuation tolerance and power ratings. Ensure compatibility with system impedance requirements of 50 Ohms. Check for any specific handling instructions related to the surface-mount package type during assembly.

Selection Notes

Select this component when a fixed 5 dB attenuation is required within a DC to 18 GHz operational bandwidth. Consider the 1.4W power handling capacity for high-signal environments. Evaluate the surface-mount form factor against available board space constraints and thermal management needs for the specific application design.

Part Context

This part belongs to Mini-Circuits' series of fixed attenuators, which are essential passive components for managing signal strength in RF and microwave circuits. These devices are typically used to prevent overload in sensitive downstream components or to improve impedance matching within transmission lines.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitute part numbers within the same series or family that offer compatible electrical specifications and physical dimensions.
