7.2 Ran Up Converter (RUC2.X or RUC3)
The RAN Up Converter (RUC), shown in Figure 2-29, takes IF signals from a DIF signal
generated by a SIF and up converts the signals to RF. The RF outputs of the RUC are
connected to the RFA’s using coax cable jumpers. The RUC is used to monitor and control the
RFA and communicates over the provided cable using I2C. The references for the RUC user
interface are shown in Table 2-20. Two versions of the RUC, the RUC2.X and RUC3, are
available.
