GPS OVERVIEW
NuWaves’ HILNA GPS is a broadband low noise amplifier designed to achieve high gain while
maintaining low noise and a high third order intercept point specifically for L1 (1575.43 MHz) and L2
(1227.6 MHz) GPS signals.
This high-performance module delivers 32 dB of gain across the frequency range of 1200 MHz to 1600
MHz with an OIP3 of +30 dBm and less than 1 dB of noise figure. The HILNA GPS is also usable up to
2000 MHz with over 28 dB of gain.
HILNA GPS’s robust power supply also operates over a very broad range easily allowing the unit to be
integrated into systems without regard to power supply precision.

3 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 GPS 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 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 adaptors are available for most
coaxial connector types.
3.2 POWER SUPPLY
The HILNA GPS 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 an industry standard 2 mm circular connector. The only restrictions on the power source for the
unit are:
- Capable of sourcing 80 mA of current
- Capable of sourcing +5 VDC to +20 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.
3.3 CONNECTIONS
Caution: Do not apply RF to the unit until after all cable connections are made and power has been
applied.
Making the connections from the HILNA GPS is easily accomplished:
1. Connect the "RF OUT" connector on the unit to a 50 coaxial cable
2. Apply power to the unit by first plugging in the power cable sent with the unit into the DC power
input.
3. Connect the red lead to the positive side of the power supply and connect the black lead to the
negative side of the power supply. Power is now ready to be applied to the unit.
4. Connect the RF Source to the RF Destination with a second 50 coaxial cable.
5. Apply RF to the input cable assembly.
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.

Powering down the unit is done by reversing this procedure.
Connection Summary:
Connect the RF Output to a good load. The characteristic impedance is 50 Ω.
Apply DC (+12 VDC Typical) at the power connector.
Connect an RF source to the RF Input connector.
Caution: Excess drive levels at the input to the amplifier can permanently damage
the unit. Under no circumstance should the RF Input level exceed +20 dBm.
3.4 ENVIRONMENTAL SPECIFICATIONS
The HILNA GPS units are rated for operation from -20 to +70 °C. The enclosure is NOT watertight so the
unit must be kept dry. It is recommended that the unit be installed in a well-ventilated area or mounted
to a heat sink if the input voltage exceeds +12 VDC. The unit will run warmer as the input voltage
increases.
