The Model 6451 Headend Driver
Amplifier is an indoor device for use
in the headend or hub. The Model
6451 features a feedforward gain
block at 550 MHz. It is housed in a
compact (3.25 in. x 4.00 in. x 6.50 in.)
module that can be attached to a pre-
drilled P-3 panel for mounting in a
standard headend rack. An optional
pre-drilled panel is available that
allows access to test points from the
front of the headend rack. The
feedforward gain block provides
exceptional distortion performance at
operational output levels. 

The Model 6451 can be powered with
most standard AC voltages and can
be configured to utilize 24 V DC
powering (jumper selected).
