The DUC864 upconverter is designed specifically to upconvert a 44 MHz IF signal, modulated by a digital signal utilizing either 8-VSB or QAM modulation, without degradation to the digital transport stream that is ultimately recovered. The DUC864 can supply an output on any channel between 54 and 860 MHz. CATV or broadcast channel plans may be selected by a front panel switch. The DUC864 is packaged in an extruded aluminum case to be utilized with other Drake Digital component series products.
