  • Page 45: Lightning Protection

    DSPBR User’s Manual DC connection to the DSPbR® is via a two terminal 85 Amp rated polarised modular Phoenix connector block (Phoenix model number HDFK 16A). The polarised DC power cables must be rated to carry the required current with minimal voltage drop. We recommend the use of 10AWG gauge cable up to 10 meters in length for the 48VDC supply option and 6AWG cable of the same length (up to 10m) for the 24VDC supply option.

  • Page 131: Multi-Carrier Power Amplifier (Mcpa)

    Multi-Carrier Power Amplifier (MCPA) Operation The RFI DSP based repeater (DSPbR®) is designed to accommodate up to eight RF power amplifier back-end modules (RFBE’s). Each RFBE module has two sides, Side A and Side B, with each side having a separate power amplifier. The power amplifiers in each RFBE module can produce up to 46dBm output power per carrier (frequency band and modulation scheme dependent) when configured for a single carrier.

  • Page 132: Number Of Carriers

    DSPBR User’s Manual Figure 30: Example of RFBE’s performance with 12 carriers The example represented in Figure 30 shows 12 carriers configured to pass through one RF power amplifier. The blue Australian ‘ACMA Compliant’ trace shows that with 13dBm per carrier, the worst case IMD products are not exceeding the required - 30dBm level.

  • Page 133: Configuring The Mcpa Feature

    DSPBR User’s Manual As can be seen in the illustration, when the number of carriers is reduced from 12 to 8, the power per carrier can be increased by 2dB and still comply with the example ACMA -30dBm spurious emission limit. If the number of carriers is further reduced to 4 (see Figure 3), the RF output power can be increased to 17dBm per carrier.
