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,...etc frequency range.

The specification ranges from 5 MHz to 1000 MHz, with an average of 100 mW, a peak of 200 mW, excellent return loss (> 20dB) 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.

Now, the frequency support to 1218 MHz is also available, please specify when ordering.
