RF Forward Path Amplifier - Standard


About the Product

The RF Forward Path Amplifier - Standard (FPAS) is designed to plug into PBN's latest generation Advanced Intelligent Multi-services Access platform - the AIMA3000.

The FPAS accepts forward-path RF signals from 45 MHz to 1218 MHz through the RF input port.

Electronic gain and slope control allows for the module to be customized for many situations.

The forward-path version provides Automatic Gain Control (AGC). The FPAS can also be conveniently monitored and controlled through a computer connected to one of the Ethernet ports via the ASMM module.

All module settings are retained in non-volatile memory to ensure trouble-free operation. Bulk updating, automatic uploading and downloading of configuration files can be done when using PBN's NMSE web-based management system.

  • DOCSIS 3.1 Compatible with operating bandwidth up to 1218 MHz
  • Plug-and-play with the AIMA3000 platform
  • Supports both digital and analog transmissions
  • High linearity, superior low noise profile, and minimal distortion
  • Automatic gain control (AGC) or manual gain control (MGC)
  • Electronic gain and slope control
  • Configurable alarm thresholds
  • Alarm monitoring through PBN's NMSE and the ASMM's Web Interface
  • 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
