Microwave Precision Fixed Attenuator 50 Up to 2W YAT-SERIES DC to 18 GHz The Big Deal * Exceptional Power Handling, Up to 2W * Wide bandwidth, DC - 18 GHz * Small Size, 2 mm x 2 mm CASE STYLE: MC1630 Product Overview YAT attenuators (ROHS compliant) are fixed value, absorptive attenuators fabricated using highly repetitive MMIC processing including thin film resistors on GaAs substrates. YAT attenuator die contain throughwafer 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 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 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 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. Notes A.
