The Big Deal
• Exceptional Power Handling, Up to 2W
• Wide bandwidth, DC - 18 GHz
• Small Size, 2 mm x 2 mm
Product Overview
YAT attenuators (ROHS compliant) are xed value, absorptive attenuators fabricated using highly repeti-
tive MMIC processing including thin lm resistors on GaAs substrates. YAT attenuator die contain through-
wafer Cu metallization vias to realize low thermal resistance and wideband operation. YATs are available
with nominal attenuation values of 0 to 10 dB (in 1 dB steps), and 12, 15, 20, and 30 dB. Packaged in tiny
2 mm x 2 mm MCLPTM package ts into tiny spaces.
Feature Advantages
Wideband operation, DC to 18 GHz
Supports a wide array of applications including wireless cellular, microwave communi-
cations, satellite, defense and aerospace, medical broadband and optic applications.
Small Size and simple to use
(2 mm x 2 mm)
As a single chip solution, the YAT series occupies less board space than a “T” or “Pi” pad
conguration, and ensures repeatable performance over wide frequency ranges.
High Power, Up to 2W
High power handling in a small size package.
Wide range of nominal attenuation values
0 to 10 dB (in 1 dB steps), and 12, 15, 20,
and 30 dB
Small increment offering enables circuit designer to change attenuation values without
motherboard redesign making the YAT series ideal for select at test application.
MCLPTM Package
Low Inductance, repeatable transitions, excellent thermal path make the YAT series an
ideal solution as an alternative to “do it yourself” resistor based attenuators.
