Signal Combining Methods

6

T

he output levels of the modulator should be

the same as the output of the off-air strip ampli-
fiers. The

PM45

modulators are usually com-

bined with either the

SP860

signal processor,

LBS/MBS/FMSEP/UBS

series strip amplifi-

ers. Three methods are suggested
to combine strip amplifier, modu-
lator and processor outputs.

T

he

PHC-12U

twelve channel passive headend

combiner

consists of two rows of directional

couplers  combined  by  a  hybrid  splitter.    The
directional  coupler  combining  provides  high
isolation  (40  dB)  between  the  inputs.    Nor-
mally, the odd channels are combined on one
row while even channels are combined on the
other  row  of  directional  couplers.    The  com-
biner loss is 16 dB per channel.

T

he

CHC-16U/860

sixteen channel active

headend combiner provides both signal com-
bining and post amplification of the headend
signals. Up to 16 channels may be combined
using the

CHC-16U/860

. The combiner gain is

10 dB per channel.

T

he final method of combining signals uses

three hybrid splitters per headend rack. The
odd channels are combined in one splitter, the

even-channels in another splitter and the two splitters are combined to a
single output with a third splitter. Each rack is then combined with a final
splitter prior to the

CA-30RK860

post amplifier.
