T
–
3+ is an absorptive fixed attenuator fabricated using highly reliable and repeatable GaAs MMIC IPD process. The model
operates from DC to 43.5GHz. It achieves outstanding attenuation accuracy and flatness while maintains excellent VSWR
throughout the entire band. The model can also handle input power up to 2W, which makes this model an ideal choice for a
wide range of applications.

Feature
Advantages
Supports a wide array of applications including 5G, wireless infrastructure, microwave communications,
satellite, defense and aerospace, medical broadband and optic applications.
Wideband operation, From DC to 43.5 GHz
Small Size and simple to use
(2 mm x 2 mm)
As a single chip solution, the KAT series occupies less board space than a lumped element approach, minimizes
component count and ensures repeatable performance over wide frequency range.
Wide range of nominal attenuation values
(0,1,2,3,4,5,6,7,8,9,10,12,15,20 & 30)
Small increment offering enables circuit designer to change attenuation values without motherboard redesign
making the KAT series ideal for select at test application.
Low Inductance, repeatable transitions, excellent thermal path make the KAT series an ideal solution as an
alternative to “do it yourself” lumped element-based approach.
