The Big Deal

• Ultra-wide band, DC to 43.5 GHz

• Excellent power handling, up to 2W

• Contiguous ground plane for easy installation

Product Overview

Mini-Circuits’ KAT-D-series MMIC attenuator dice (RoHS compliant) are fixed value, absorptive attenuators

fabricated using highly repetitive MMIC processing with thin film resistors on GaAs substrates. Providing

precise attenuation from DC up to 43.5 GHz, these attenuators are ideal for a very wide range of applica-

tions up to millimeter wave bands including 5G systems and more. KAT-D-series attenuator dice are avail-

able from stock with nominal attenuation values of 0 to 10 dB (in 1 dB steps), and 12, 15, 20, and 30 dB.

Feature

Advantages

Ultra-wide band operation, DC to 43.5 GHz

KAT-D-series attenuator dice support a wide array of applications including 5G sys-

tems, microwave communications, satellite, defense and aerospace, medical broad-

band and optical applications

Single, contiguous ground plane

The attenuators achieve ultra-wide band performance up to 43.5 GHz with single,

contiguous ground plane, simplifying installation into customer hybrids.

High power handling, up to 2W

Power handling up to 2W makes KAT attenuator dice suitable for a wide range of

system power requirements.

Wide range of nominal attenuation values:

0 to 10 dB (in 1 dB steps) and 12, 15, 20

and 30 dB

Small increment offerings enable circuit designers to change attenuation values with-

out motherboard redesign, making the KAT-D-series ideal for adjusting attenuation

values based on test results.

Excellent attenuation flatness

Provides precise, consistent attenuation across the entire frequency band, ideal for

broadband and multi-band usage.
