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.
3.1
CABLING
The
HILNA LS-C026
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 connectors 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
without adequate filtering in place.
If cables with the SMA‐type connectors are not available, high quality adaptors are available for most
coaxial connector types.
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
are power and ground feed through pins
. The only restrictions on the power source for the
unit are:
- Capable of sourcing 300mA of current
- Capable of so5 VDC to +8 VDC
Car batteries (through a cigarette lighter adaptor), laboratory DC power supplies, or wall transformers
are suitable power sources as long as the superimposed ripple is low in amplitude.
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.
