Introduction
The AT2 series is a wideband attenuator with DC block.
Its superior specifications enable it to meet the needs of all attenuation or impedance matching applications in the TV, CATV, DOCSIS, MoCA, satellite-IF,...etc frequency range.
The specification ranges from 5 MHz to 3 GHz, with an average of 100 mW, a peak of 200 mW, excellent return loss 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.
