LNA Low-Noise Amplifier Series Revision 1
Introduction MN/LNAS.IOM
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 accommodate systems ranging from Very Small Amplifier Terminal (VSATs) to major
earth stations.
Figure 1-1. LNA: Left, C-Band Low-Noise Amplifier; Right, Ku-Band Low-Noise Amplifier
1.2 Technology
The amplifiers incorporate both HEMT (High Electron Mobility Transistors) devices for Low-Noise
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.

LNA Low-Noise Amplifier Series Revision 1
Introduction MN/LNAS.IOM
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.

Chapter 2. INSTALLATION
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.
Do not use any cutting tool that will extend more than 1 inch into the container.
This can cause damage to the LNA.
Do these steps:
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.
2.2 Installation Tools
No special tools are required.

4.3 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.
4.4 Cables and Connectors
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, make sure 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.
4.5 Operating Requirements for Regulatory Compliance
To maintain continued compliance with the European Directives:
• Make connections to the Tx and Rx IF ports (Type N or Type F connectors using a good quality
coaxial cable - for example 50 Ω or 75 Ω.
• Make sure all D type connectors attached to the rear panel 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.
• Make sure the equipment operates with its cover on at all times. If it becomes necessary to
remove the cover, make sure that the cover is correctly reinstalled before normal operation
resumes.
