The MB1200 can work either as a line amplifier or as a bridger amplifier - the mode can be set by using jumpers.
This makes possible to utilize the low power consumption and the high adaptaibility at the same device. Thanks to
the module based breakpoint setup and the ASG automatic this type can be used in any coaxial network. The
flexibility is improved by the 4th RF port, which can be configured as an input bypass port or a 3rd output.

Benefits :- 

• Downstream frequency range up to 1218 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• GaN output stage
• Automatic gain and slope control
• Automatic ingress management by the RSW module
