The XAT-4+ sets a new benchmark in RF component miniaturization as the smallest MMIC attenuator by virtue of its 2-lead, 1×1 mm QFN package, which enables unprecedented space savings in next-generation high-density PCB designs. Fabricated on a robust GaAs semiconductor process, its bidirectional, fully absorptive design delivers exceptional passband flatness, maintains excellent return loss throughout the entire band, and delivers consistent and repeatable performance from DC to 45 GHz. With up to 2 W input power handling, the XAT-4+ is perfectly suited for space-constrained, high frequency applications, including Test & Measurement, Satellite Communications, Radar Systems, EW/ECM Defense Systems, Telecom Infrastructure, and 5G networks.
