KAT-1+

Overview

The KAT-1+ is a monolithic microwave integrated circuit (MMIC) fixed attenuator manufactured by Mini-Circuits. It provides a nominal attenuation of 1 dB with a maximum specified attenuation of 1.8 dB across a frequency range from 0 Hz to 43.5 GHz. The component operates at a standard system impedance of 50 ohms and features a maximum voltage standing wave ratio (VSWR) of 1.9. Designed for surface mount applications, it utilizes the MCLP-6 package configuration. The device supports a power handling capacity of 2 watts and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Ultra-wideband operation extending from DC up to 43.5 GHz
• Compact MCLP-6 surface mount package design
• Monolithic microwave integrated circuit construction

Applications

• RF signal path attenuation in high-frequency circuits
• Impedance matching networks in microwave systems
• Signal level control in test and measurement equipment

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct pinout and electrical specifications. Confirm that the MCLP-6 package dimensions align with your PCB footprint requirements. Check the latest datasheet for any updates regarding thermal performance or reliability standards before finalizing procurement orders.

Selection Notes

Select this component when a precise 1 dB attenuation value is required over a broad bandwidth up to 43.5 GHz. Ensure the application environment stays within the specified -40°C to +85°C temperature range. Verify that the 50-ohm system impedance matches your circuit design and that the 2-watt power rating exceeds the expected signal levels.

Part Context

This component belongs to the KAT series of fixed attenuators from Mini-Circuits, which offers various attenuation values and frequency ranges. The KAT-1+ specifically addresses low-loss applications requiring minimal signal reduction while maintaining wideband performance. It complements other MMIC attenuators in the portfolio designed for compact RF and microwave module implementations.

Replacement Considerations

Direct substitutes include other Mini-Circuits models such as the KAT-1-D die version for custom packaging needs. Cross-manufacturer replacements require careful verification of S-parameter data, package outline dimensions, and thermal characteristics to ensure functional equivalence in high-frequency designs.
