Preface MN/LNAS.IOM
Electrical Safety
The LNA Low Noise Amplifier Series has been shown to comply with the following safety
standard:
• EN 60950: Safety of Information Technology Equipment, including electrical
business machines
The equipment is rated for operation over the range 100 - 240 volts AC. It has a maximum power
consumption of 60 watts, and draws a maximum of 600 mA.
The user should observe the following instructions:
IMPORTANT
Fuses
The LNA is fitted with two fuses - one each for line and neutral connections. These are contained
within the body of the IEC power inlet connector, behind a small plastic flap.
• For 115 and 230 volt AC operation, use T1.25A, 20mm fuses.
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH
THE CORRECT TYPE AND RATING.
Environmental
The LNA must not be operated in an environment where the unit is exposed to extremes of
temperature outside the ambient range 0 to 50°C (32° to 122°F), precipitation, condensation, or
humid atmospheres above 95% RH, altitudes (un-pressurized) greater than 2000 metres,
excessive dust or vibration, flammable gases, corrosive or explosive atmospheres.
Operation in vehicles or other transportable installations that are equipped to provide a stable
environment is permitted. If such vehicles do not provide a stable environment, safety of the
equipment to EN60950 may not be guaranteed.
Installation
The installation and connection to the line supply must be made in compliance to local or national
wiring codes and regulations.
vi
LNA Low Noise Amplifier Series Revision 0
Preface MN/LNAS.IOM
The LNA is designed for connection to a power system that has separate ground, line and neutral
conductors. The equipment is not designed for connection to power system that has no direct
connection to ground.
The LNA is shipped with a line inlet cable suitable for use in the country of operation. If it is
necessary to replace this cable, ensure the replacement has an equivalent specification. Examples
of acceptable ratings for the cable include HAR, BASEC and HOXXX-X. Examples of
acceptable connector ratings include VDE, NF-USE, UL, CSA, OVE, CEBEC, NEMKO,
DEMKO, BS1636A, BSI, SETI, IMQ, KEMA-KEUR and SEV.

EMC (Electromagnetic Compatibility)
In accordance with European Directive 89/336/EEC, the LNA Modem has been shown, by
independent testing, to comply with the following standards:
Emissions: EN 55022 Class B - Limits and methods of measurement of radio interference
characteristics of Information Technology Equipment.
(Also tested to FCC Part 15 Class B)
Immunity: EN 50082 Part 1 - Generic immunity standard, Part 1: Domestic, commercial and
light industrial environment.
Additionally, the LNA has been shown to comply with the following standards:
EN 61000-3-2 Harmonic Currents Emission
EN 61000-3-3 Voltage Fluctuations and Flicker
EN 61000-4-2 ESD Immunity
EN 61000-4-4 EFT Burst Immunity
EN 61000-4-5 Surge Immunity
EN 61000-4-6 RF Conducted Immunity
EN 61000-4-8 Power Frequency Magnetic Field Immunity
EN 61000-4-9 Pulse Magnetic Field Immunity
EN 61000-4-11 Voltage Dips, Interruptions, and Variations Immunity
EN 61000-4-13 Immunity to Harmonics
In order that the Modem continues to comply with these
standards, observe the following instructions:
IMPORTANT
• Connections to the Tx and Rx IF ports (Type N or Type F connectors) should be
made using a good quality coaxial cable - for example 50 Ω or 75 Ω.
• All 'D' type connectors attached to the rear panel must have back-shells that provide
continuous metallic shielding. Cable with a continuous outer shield (either foil or
braid, or both) must be used, and the shield must be bonded to the backshell.
• The equipment must be operated with its cover on at all times. If it becomes
necessary to remove the cover, the user should ensure that the cover is correctly refitted before normal operation commences.

Chapter 1. INTRODUCTION
1.1 Introduction
The Comtech EF Data (CEFD) Low-Noise Amplifier (LNA) series (Figure 1-1) includes LNAs,
available in C-Band and Ku-Band. They meet or exceed system requirements for commercial
geosynchronous satellites worldwide. Their compact design and rugged construction make them
ideal for transportable applications and severe environments. They have a comprehensive set of
options to accom-modate systems ranging from Very Small Amplifier Terminal (VSATs) to
major earth stations.

LNA Low-Noise Amplifier Series Revision 0
Introduction MN/LNAS.IOM
1.2 TECHNOLOGY
The amplifiers incorporate both HEMT (High Electron Mobility Transistors) devices for LowNoise temperature performance and GaAs FET (Gallium Arsenide) devices for low
intermodulation. The unit uses surface mounted components for robotic manufacturing
techniques, thereby insuring maximum product consistency and enhanced reliability.
1.3 RELIABILITY
The Comtech EF Data amplifier series (CLNA and KLNA) utilizes proprietary circuitry and high
quality components to achieve an MTBF (mean time between failures) in excess of 160,000
hours. Each unit is subjected to a 72 hour burn-in and temperature cycled from -40 to 140°F
(-40 to +60°C).
1.4 CONSTRUCTION
The LNAs (CLNA and KLNA) are housed in waterproof enclosures with a small profiles to
better accommodate redundancy configurations. The enclosures also provide a pressurizable,
integral waveguide flange.

2.1 Unpacking
Inspect shipping containers for damage. If shipping containers are damaged, keep them until the
contents of the shipment have been carefully inspected and checked for normal operation.
The modulator and manual are packaged in pre-formed, reusable, cardboard cartons containing
foam spacing for maximum shipping protection.
CAUTION
Unpack the LNA as follows:
Step Procedure
1 Cut the tape at the top of the carton indicated by OPEN THIS END.
2 Remove the cardboard/foam space covering the LNA.
3 Remove the LNA, and manual from the carton.
4 Save the packing material for storage or reshipment purposes.
5 Inspect the equipment for any possible damage incurred during shipment.
6 Check the equipment against the packing list to ensure the shipment is correct.
7 Refer to the following sections for further installation instructions.
Chapter 2. INSTALLATION
Do not use any cutting tool that will extend more than 1 inch into the
container. This can cause damage to the LNA.
