The Drake Digital system features a flexible, modular approach for the
reception and redistribution of Digital signals for CATV and Private Cable.
The units can receive and decode or transcode all the MPEG signals such
as QPSK, 8-VSB, and ATSC for retransmission in QAM or analog format.
TMQAM
QAM Modulator
The TMQAM QAM Modulator is a professional quality,
modular, digital, headend component designed to provide
optimum performance with minimized rack space requirements.
The modulator accepts a MPEG2 transport stream input in
the SPI format and is capable of providing a QAM output with
16, 32, 64, 128 or 256 constellation points.

SDQPSK
Digital Satellite Demodulator
The SDQPSK Digital Satellite Demodulator is a professional quality,
modular, digital, headend component designed to provide optimum
performance with minimized rack space requirements. This demodulator receives a PSK modulated signal (usually it will be QPSK) in
the L Band range of 950-2150 MHz and demodulates the signal
providing an MPEG-2 transport stream digital output. The SDQPSK
easily interfaces to the Drake QAM modulator or SD/HD decoder
modules via a standard 25 conductor data cable (SPI interface).

display allow easy setup of
operating parameters.

rack mount.
DDC806
Digital Downconverter
The DDC806 is a low noise downconverter designed for translating digital signals from their off-air or CATV channel to a 44 MHz IF output. The
output of the DDC806 can be connected to a DUC series upconverter to
place the digital signal on a new output channel. the DDC806 may be
used with VSB, QAM, or QPSK digital signals. VSB signals up to
16VSB and QAM signals up to 256QAM may be translated. The channel bandwidth is fixed at 6 MHz. The DDC806 provides low noise figure
and low phase noise as well as a flat passband to minimize signal dete-
