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.
