The model DPAT-135145-32-08-0.125 is a digital phase invariant attenuator that covers the frequency range from 13.5 to 14.5 GHz. As the attenuation is varied over its entire 32 dB range the phase shift remains within a maximum of 7°. The insertion loss is less than 2.5 dB and attenuation is performed in steps of 0.125 dB. The attenuator is controlled by an 8-bit digital word with an accuracy of 1 dB. Options available include attenuation ranges to 60 dB and other frequency bands.
