INSTALLING, CONNECTING, AND USING THE HILNA AMPLIFIER
HILNA amplifiers have been designed to be highly reliable under the specified operating conditions. The
following installation and interfacing guidelines should be followed to prevent damage to the RF
module.
The
HILNA LS C021-D
is equipped with high‐performance RF connectors. Gold plated SMA‐type
receptacles are used
because
they
perform
very
well
across
the
usable
frequency
range
of
the
unit.
For
optimal
performance, a high‐quality 50
Ω
coaxial cable with SMA‐type plugs should be used to
interface with the amplifier.
Caution: Due to the wideband nature of the unit, installation should not be attempted on a tower
with transmit antennas.
If cables with the SMA‐type connectors are not available, high quality adapt
e
rs are available for most
coaxial connector types.
The
HILNA LS C021-D
is available with an optional
built in bias‐T capability, allowing the user to supply DC
power from the RF circuitry or coaxial cables without affecting the RF signal through the main
transmission path.
Caution: Due to the bias‐T configuration, DC power will always be present on the RF output line.
3.2
POWER SUPPLY
The HILNA contains internal linear voltage regulators. These regulators protect the circuitry from voltage
variations at the input and allow for the wide operating voltage. The power connector for the units
is a
micro-D 9-
pin connector. As an option, DC power can also be applied to the RF Output port
with an external bias‐T. The only restrictions on the power source for the unit are:
‐
Capable of sourcing
13
0
mA of current
‐
Capable of so5 VDC to +15
VDC
Caution: The HILNA amplifier contains components that are sensitive
to Electro‐Static Discharge (ESD). The use of wrist strap, mats, and
ground straps should be adhered to during the installation process.
