Microwave Precision Fixed Attenuator QAT-SERIES 50 Up to 2W DC to 50 GHz The Big Deal Super bandwidth, Up to 50 GHz CASE STYLE: MC3000 Exceptional Power Handling, from 0.8W to 2W Small Size, 2 mm x 2 mm Product Overview QAT models are a series of absorptive fixed attenuators fabricated using highly reliable and repeatable GaAs MMIC IPD* process. The models operate from DC up to 50 GHz. They have outstanding attenuation accuracy and flatness while maintaining excellent VSWR throughout the entire band. The models can also handle input power up to around 2W, depending on each value, which makes this model series an ideal choice for a wide range of applications. Key Features Feature Advantages Supports a wide array of applications including 5G, wireless infrastructure, microwave Wideband operation, From DC to 50 GHz communications, satellite, defense and aerospace, medical broadband and optic ap- plications. As a single chip solution, the QAT series occupies less board space than a lumped ele- Small Size and simple to use ment approach, minimizes component count and ensures repeatable performance over (2 mm x 2 mm) wide frequency range. Wide range of nominal attenuation values Small increment offering enables circuit designer to change attenuation values without (0,1,2,3,4,5,6,7,8,9,10,12,15,20 & 30) motherboard redesign making the QAT series ideal for select at test application. Low Inductance, repeatable transitions, excellent thermal path make the QAT series an TM MCLP Package ideal solution as an alternative to do it yourself lumped element-based approach. * IPD - Integraded Passive Device.
