XAT Series　Ultra-Compact 1×1 mm MMIC Fixed Attenuator

In an ultra-compact 1×1 mm footprint, this MMIC fixed attenuator combines broadband coverage from DC to 45 GHz with input power handling of up to 2 W.

・DC to 45 GHz, 50 Ω
・Industry’s smallest-class 1×1 mm 2-terminal QFN package
・Wideband operation with flat attenuation characteristics from DC to 45 GHz
・High input power handling of up to 2 W (1.9 W for the XAT-10+)
・Excellent return loss (16 dB typical)
・Bidirectional, fully absorptive design based on a robust GaAs semiconductor process
・Pin-compatible across the entire XAT family, allowing the attenuation value to be changed without any layout modification
・Low inductance and excellent heat dissipation to the PCB
・Compatible with chip mounters and ideal for high-volume production
・Main applications: test instruments, satellite communications, radar, EW/ECM defense systems, communication infrastructure, 5G networks
