Introduction
The AT3-2xxW series is a compact size broadband attenuator.
Its superior specifications enable it to meet the needs of all attenuation or impedance matching applications in the TV, CATV, DOCSIS, MoCA,...etc frequency range.
The specifications: from 1 MHz to 2500 MHz at 100 mW average, 200 mW peak, excellent return loss(>20 dB at 1000 MHz) and good accuracy.
A list of commonly used models is as follows. If there are other attenuation value requests, please contact us, we can also design.
