SETUP AND OPERATION
This
section
provides
specific
details
for
proper
operation
of
the
NuPower
Xtender
module.
Following
these
guidelines
will
prevent
damage
to
the
bidirectional
amplifier
or
external
equipment.
3.1
POWER SUPPLY REQUIREMENTS
To
operate
the
NuPower
Xtender
C10RX01,
ensure
that
the
power
supply
has
adequate
overhead
to
source
the
current
demand
of
the
RF
amplifier.
The
power
supply
source
must
provide
a
voltage
of
+28
VDC
with
greater
than
5
amps
capability.
3.2
CONNECTING A PROPER LOAD TO THE ANTENNA TERMINAL
To
prevent
damage
to
the
amplifier
module,
the
antenna
terminal
must
be
terminated
into
a
50
Ω
load.
Examples
of
a
proper
load
include:
Directly
connecting
to
an
antenna
specified
for
the
frequency
range
(4400
to
5100
MHz).
Connecting
to
an
inappropriate
antenna
may
result
in
damage
to
the
amplifier
module.
Connecting
to
a
proper
antenna
through
a
50
Ω
transmission
line
or
coaxial
cable.
Avoid
using
damaged
cables
or
corroded
connectors
while
attaching
the
unit
to
an
antenna.
Terminating
the
antenna
terminal
into
a
50
Ω
power
attenuator
with
minimum
20
dB
attenuation.
Connecting
to
a
50
Ω
load
capable
of
dissipating
the
RF
power
from
the
amplifier
module.
Loads
capable
of
handling
30
Watts
(min)
are
recommended.
3.3
POWERING
‐
UP THE NUPOWER XTENDER
The
NuPower
Xtender
C10RX01
must
be
terminated
into
a
proper
load
before
power
is
applied.
Refer
to
Section
3.2
for
the
specifications
of
the
proper
load.
After
the
amplifier
is
properly
terminated,
the
interface
cable
can
be
connected
to
the
unit
and
power
can
be
applied.
The
amplifier
is
now
ready
for
operation.
