KAT-30+

Overview

The KAT-30+ is a fixed attenuator fabricated using a GaAs MMIC process, operating from DC to 43.5 GHz. It provides 30 dB attenuation with a 50 Ohm impedance and 1W power handling. The component features a maximum VSWR of 1.7 and operates within a temperature range of -40°C to +85°C. Packaged in a 6-TDFN exposed pad SMD format, it supports surface mount installation for high-frequency applications.

Feature Summary

• Utilizes reliable GaAs MMIC fabrication technology
• Provides wideband operation extending to 43.5 GHz
• Designed as an absorptive fixed attenuator

Applications

• High-frequency RF signal conditioning
• Microwave circuit testing and measurement
• Broadband communication systems

Procurement Notes

Verify the specific suffix against official Mini-Circuits documentation to confirm exact electrical tolerances and package variations. Ensure compatibility with standard surface mount reflow profiles. Confirm that the 6-TDFN exposed pad configuration aligns with your PCB thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a wide bandwidth up to 43.5 GHz is required alongside precise 30 dB attenuation. The GaAs MMIC construction ensures repeatability suitable for demanding environments. Consider the 1W power rating and 50 Ohm system impedance to ensure proper integration into existing RF chains without mismatch issues.

Part Context

This model belongs to Mini-Circuits' line of fixed attenuators designed for microwave frequencies. It complements other series like YAT-30A+ and RCAT-30+, offering superior frequency coverage compared to lower-bandwidth alternatives while maintaining compact surface-mount packaging for modern electronic assemblies.
