RF Return Path Amplifier - Standard


About the Product

The RPAS, RF Return-Path Amplifier - Standard series, is designed to plug into PBN's latest generation Advanced Intelligent Multi-services Access Platform - the AIMA3000.

The RPAS has two independent amplifier circuits and it accepts returnpath RF signals from 5 MHz to 204 MHz through the two RF input ports. The module has an adjustable gain range of 10 dB to 30 dB and has dual output ports.

Electronic gain and slope controls allow the module to be customized for many different configurations.

Microprocessor-based status monitoring and control is available locally and remotely through a web interface or by using PBN's NMSE (network management software). All module settings are retained in non-volatile memory to ensure hassle-free operation.

  • Plug-and-play with the AIMA3000 platform
  • Return path amplifier (5 MHz to 204 MHz) supports both analog and digital signal source
  • High linearity, superior low noise profile, and minimal distortion
  • Manual gain control (MGC)
  • Electronic gain and slope control
  • User configurable alarm threshold levels
  • Alarm monitoring
  • Broadband GaAs amplifier technology
  • Remote firmware upgrade and auto upload/download of configuration files through ASMM web interface or using PBN's NMSE
  • Fully FCC, CE, and RCM compliant
