Mini Return Path Band Attenuator
 
Introduction

The BAT4 series is our mini size return path band attenuator with high pass filter. It is designed for application in CATV system to attenuation return path signal.

BAT4 band attenuators selectively attenuate one band while not influencing the other band.

A built-in high pass filters keeps unused portions of the return path (below 15, 18 or 20 MHz) noise-free.

Typically, the return path attenuation value varies from -3dB to -15dB in 3dB increments. The common separation frequencies are 42/ 54 MHz, 65/ 85 MHz, 85/ 108 MHz and 204/ 258 MHz.

If there are other different return path attenuation values and separation frequency requests, please contact us and we can also design.
