Introduction

The AT3 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, DVB-T, ATSC, CATV, DOCSIS,...etc frequency range.

The specifications: from 1 MHz to 1218 MHz at 100 mW average, 200 mW peak, excellent return loss(>20 dB at 1000 MHz) and good accuracy.

A list of commonly used 1 GHz models is as follows. If there are other attenuation value requests, please contact us, we can also design.

The 1218 MHz models is also available, please specify when ordering.
