The R.L. Drake DUC864A is a low noise upconverter used to translate the 44 MHz digital IF signal from a QAM or
VSB modulator, DDC downconverter, or other similar equipment to the desired CATV or off-air output channel. A single
model covers the entire 54 to 860 MHz output range. The DUC864A features low phase noise and can be used for QAM
modulation up to 256 QAM. This module can be rack mounted using the RMM4 or RMM12 rack mount. The PSM 121 or
PSM 125 power supply module is required with the RMM12 (the PSM 125 provides full 12 slot capability).
NOTE:
The PS8 power supply requires an adapter part # 525148600A to power the DUC864A.
