YAT-9A+

MICROWAVE PRECISION Fixed Attenuator 50Ω 1.1W 9 dB YAT-9A+ DC to 18 GHz THE BIG DEAL y Exceptional Power Handling y Wide bandwidth, DC-18 GHz y Miniature package MCLP™ 2 x 2 mm y Excellent attenuation accuracy & flatness Generic photo used for illustration purposes only CASE STYLE: MC1630 +RoHS Compliant The +Suffix identifies RoHS Compliance. See our web site for RoHS Compliance methodologies and qualifications APPLICATIONS y Cellular y PCS y Communications y Radar y Defense 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. REV.
