KAT-15+

Overview

The KAT-15+ is a surface-mount fixed attenuator manufactured by Mini-Circuits, designed for high-frequency RF and microwave applications. It provides a nominal attenuation of 15 dB with a tolerance range of 14.5 to 16 dB across an operational frequency spectrum from DC to 43.5 GHz. The component features a 50-ohm impedance and supports a maximum power handling capacity of 1.4 W. It exhibits a maximum Voltage Standing Wave Ratio (VSWR) of 1.9, ensuring efficient signal transmission. The device operates within a temperature range of -40°C to +85°C and utilizes a 6-TDFN exposed pad package for reliable SMT integration.

Feature Summary

• Provides stable 15 dB attenuation across a wide bandwidth extending to 43.5 GHz
• Supports 1.4 W power handling in a compact surface-mount footprint
• Maintains low VSWR for minimal signal reflection in 50-ohm systems

Applications

• RF signal level control in wireless communication infrastructure
• Test and measurement equipment requiring precise attenuation
• Microwave circuit design for satellite communications

Procurement Notes

Verify the specific datasheet version and electrical performance graphs provided by Mini-Circuits or authorized distributors before finalizing designs. Confirm that the 6-TDFN package dimensions and thermal pad requirements align with your PCB layout specifications. Ensure that the operating environment remains within the specified -40°C to +85°C temperature range to maintain rated performance and reliability standards.

Selection Notes

Select the KAT-15+ when a fixed 15 dB attenuation is required at frequencies up to 43.5 GHz. Consider its 1.4 W power rating and 50-ohm impedance match for system compatibility. Evaluate the 6-TDFN package size against available board space constraints. Compare VSWR specifications against other attenuators if strict return loss performance is critical for the application.

Part Context

The KAT-15+ belongs to Mini-Circuits' extensive portfolio of RF and microwave components, specifically within their fixed attenuator line. This series is engineered for high-performance applications demanding stability and precision. The component represents a solution for integrating passive attenuation directly into surface-mount circuits without requiring bulky through-hole alternatives.
