The R.L. Drake DUC864 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 DUC864 features
low phase noise and can be used for QAM
modulation up to 256 QAM. This module can be
rack mounted using the DRMM4 or DRMM12
rack mount. The PS8 power supply module is
required with the DRMM12.

indicates an invalid channel setting or other
conditions that would cause the unit to operate
on an invalid channel. The RF output is
switched off for flashing (ERROR) conditions.
F2 - Channel Number Switch
Sets the desired operating channel for standard
CATV or Broadcast channel plans. See also
Item F3 which sets the type of channel (CATV
or Broadcast TV) and sets the leading “1” for
CATV channels 100 through 135.
F3 - Channel Mode Switch

RACK MOUNTING
Adequate ventilation is very important in
multichannel installations. Units should be
spaced apart by at least one panel height
wherever possible, and some air movement is
mandatory in enclosed rack cabinets. Excessive heat will shorten component life and
modulator performance will be degraded
without proper cooling.

R1 - IF INPUT Connector
This is the 44 MHz IF input. The required level
is +30 dBmV (from TMQAM or DDC, etc).
R2 - DC INPUT Connector
This 3-pin connector (Male) accepts the
appropriate mating DC power cable. Observe
proper orientation and wiring.
R3 - RF OUTPUT Connector
This is the upconverter output.

DESCRIPTION
Figure 3 shows a typical installation utilizing 4
DUC864 upconverters used with 4 TMQAM
modulators. A PS8 power supply module is
used to power all units.

RACK MOUNTING
Adequate ventilation is very important in
multichannel installations. Units should be
spaced apart by at least one panel height
wherever possible, and some air movement is
mandatory in enclosed rack cabinets. Excessive heat will shorten component life and
modulator performance will be degraded
without
proper cooling.
