PRODUCT OVERVIEW
YAT-A attenuators (ROHS compliant) are fixed value, absorptive attenuators fabricated using highly repetitive MMIC processing
including thin film resistors on GaAs substrates. YAT-A attenuators contain through-wafer metallization vias to realize low
thermal resistance and wideband operation. YAT-As 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 fits into tiny spaces.
KEY FEATURES
Feature
Advantages
Wideband operation, DC to 18 GHz
Supports a wide array of applications including wireless cellular, microwave Communications, 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-A series occupies less board space than a “T” or “Pi” pad configuration, 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-A series ideal for select at test application.
MCLPTM Package
Low Inductance, repeatable transitions, excellent thermal path make the YAT-A series an ideal solution as an
alternative to “do it yourself” resistor based attenuators.
