  • Page 9: Bd Series Introduction

    RFI BD Series BDA User’s Manual BD Series Introduction RFI's UHF Bi-Directional Amplifier (BDA) is a compact IP-rated wall or pole mountable, RF- transparent repeater. The BDA is ideal for rebroadcasting RF coverage in confined areas such as in tunnels and mining sites as well as remote locations. Depending on the model, the internal duplexers can either pass a 5MHz or 1.5MHz window in each direction in the...
  • Page 10 External filtering is required for >70dB gains to provide the required isolation for the BDA. RF over Fibre (RFoF): BD series BDAs are also available with the optional RF over Fibre interface. When RFoF is used, normally two BDAs are required. One BDA will be the headend unit and will be installed near the donor RF site.

  • Page 27: Rf Level Configuration

    RFI BD Series BDA User’s Manual RF Level Configuration The RF output of the BD Series BDA is adjusted on the BDASC module. This is specified as a composite RF power rating. For example, in the standard models, the BDASC can provide a maximum +22dBm for a single carrier, or 12dBm per carrier (total of 15dBm) for six (6) carriers.
  • Page 28 RFI BD Series BDA User’s Manual A nominated “Target Value” in dBm for the path’s RF output level is nominated via the Command Line Interface (CLI). When this output level is reached, the BDASC will utilise the remaining attenuator range to prevent that RF output level from increasing further if the input signal level increases.
