KAT-2+

Overview

The KAT-2+ is a surface-mount MMIC fixed attenuator manufactured by Mini-Circuits, providing a nominal attenuation of 2 dB. It operates over a wide frequency range from DC to 43.5 GHz with a 50-ohm impedance. The device features an MCLP-6 package and supports a maximum power handling of 2 watts. It maintains a maximum VSWR of 1.9 and functions within a temperature range of -40°C to +85°C.

Feature Summary

• MMIC technology enables compact surface-mount integration for high-frequency applications
• Wide bandwidth operation extending from DC up to 43.5 GHz
• Robust power handling capability rated at 2 watts

Applications

• RF signal path attenuation in microwave circuits
• Impedance matching networks requiring precise loss values
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific datasheet revision and ordering suffix when sourcing. Confirm that the MCLP-6 package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the 2-watt power rating during continuous operation. Cross-reference the manufacturer's latest specifications to confirm compliance with current RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2 dB loss is required across a broad millimeter-wave spectrum. The MMIC architecture offers superior consistency compared to discrete resistor networks. Consider the 43.5 GHz upper limit against your system's highest operating frequency. Evaluate the MCLP-6 package size constraints relative to available board space and assembly capabilities.

Part Context

This part belongs to Mini-Circuits' KAT series of SMT fixed attenuators. These components utilize monolithic microwave integrated circuit technology to deliver stable performance in small form factors. The series covers various attenuation values while maintaining consistent electrical characteristics across the frequency band.

Replacement Considerations

RCAT-02+ serves as a potential alternative for lower frequency applications up to 20 GHz. Verify that the reduced bandwidth and different package style meet your design requirements before substituting.
