  • Page 170 Operation Addendum, Block Upconverter Operation Addendum, Block Upconverter Overview The function of the BUC (Block Upconverter) is to convert the baseband input from a modem at an IF (intermediate frequency) to the system transmit frequency. The BUC accepts an intermediate frequency, mixes it with a highly stable LO (local oscillator) and passes it through a series of circuits that filter and amplify the signal to produce an output in the desired transmission band.
  • Page 171 Operation Addendum, Block Upconverter Functional Description The block diagram in Figure 3 provides a schematic for the BUC. The input of the BUC provides diplexing to direct the reference frequency to the LO Synthesizer and IF frequency to the mixer. The synthesizer generates the LO frequency from the reference frequency and filters it to eliminate unwnated harmonics.
  • Page 172 Operation Addendum, Block Upconverter Figure 3, Detailed BUC Block Diagram Setup and Turn On In the normal operating condition the modem provides both L-Band and 10 MHz reference inputs. Other BUC configurations have a built-in (internal) 10 MHz references which operate as either standalone or phase locked to the 10 MHz input provided by the modem.
  • Page 173 Operation Addendum, Block Upconverter The output frequency accuracy depends on the accuracy of the refer- ence and IF frequencies. The determining ratios for the frequency Bands are: Ku Band — (12.8 GHz / Reference Frequency) X Reference • Offset = Output Offset. C Band —...
  • Page 174 Operation Addendum, Block Upconverter Reference Oscillator Drift Compensation Over extended time periods, the 10MHz reference oscillator changes frequency due to temperature / aging and results in a shift in the output frequency that can exceed +/- 10kHz. Depending on the system budget, the converter must be re-adjusted to stay within its allocated transponder band and within the receiver acquisition range.
