Ampli ers for in-house distribution
138
AL 223, AL 325, AL 331, AL 431
In-house amplifi er with active 65 MHz return path
different forward path gain levels; integrated return path amplifi er and diplexfi lter
attenuator for level adjustment in the input of forward and return path
equalizer in the input of the forward path
high modulation of return path to achieve operation safety even at multi channel load
integrated equalizer in forward and return path
