KAT-12+

Overview

The KAT-12+ is a fixed RF attenuator manufactured by Mini-Circuits, providing a nominal attenuation of 12 dB. It operates over a frequency range from 0 Hz to 43.5 GHz with a 50 Ohm impedance. The device features a 6-TDFN exposed pad package and supports a maximum power handling of 1.1W. It is designed for surface-mount integration in high-frequency circuits.

Feature Summary

• Provides precise 12 dB signal attenuation across a super-wide bandwidth extending into millimeter-wave frequencies.
• Utilizes a compact 2x2 MCLP™ surface-mount package for efficient PCB space utilization.
• Features an exposed pad design to facilitate thermal dissipation and secure mounting.

Applications

• RF signal level control in microwave test and measurement equipment
• Attenuation stages in S-band upconverter assemblies
• Impedance matching networks in satellite communication systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct package style and tape-and-reel configuration. Confirm that the required frequency range and power handling capabilities align with the system specifications before finalizing the component selection.

Selection Notes

Select this component when a fixed 12 dB attenuation is required at frequencies approaching 43.5 GHz. Ensure the circuit design accommodates the 6-TDFN exposed pad footprint and provides adequate thermal management for the specified power levels.

Part Context

This part belongs to the KAT series of MMIC attenuators from Mini-Circuits, which are designed for broadband applications. The series offers various attenuation values within a small form factor, supporting designs from DC through millimeter-wave ranges.

Replacement Considerations

The KAT-12-DG+ is a documented alternative variant offering similar 12 dB attenuation performance. Verify package compatibility and electrical specifications when considering substitution.
