A member of our popular MDA compact product family suited to the DOCSIS 3.1 frequency band. Beyond it's
extended bandwidth the device provides all the advantages of the predecessor type, like the
low power consumption, the high output RF level and the very easy alignment. Further the return path chain of
the amplifier contains a universal expansion socket, which can take in an HMS transponder, an auxiliary filter or
the switching module of our cost effective network management solution called RIB.

Benefit :- 

• Downstream frequency range up to 1218 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• Cost-effective solution
• Replaceable diplex kilter
• Alignment by JXP modules
