ColorConnect™ color-coded precision coaxial attenuators (AT-series) are used to reduce the power of a RF, MW or mmW signal without distorting its signal quality/waveform. Attenuators are often used to lower the amplitude of a signal to a measurable level or to protect a measurement instrument from damage. Attenuators are also used to improve matching between components by improving the return loss (twice insertion loss) and effectively reducing the VSWR seen by adjacent components. AT-series precision coaxial attenuators employ color-coded connectors to reduce potential for connection mistakes and are available with SMA, 2.92mm, 2.4mm and 1.85mm connectors up to 65 GHz.
