The Comtech EF Data (CEFD) Low-Noise Amplifier (LNA)
series includes LNAs and redundant LNA systems (C- or
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.
The C- or Ku-Band redundant LNA systems include
primary and backup LNAs and an automatic switching
controller. In case of primary LNA failure, fast automatic
switchover to the backup LNA minimizes "down" time.
The amplifiers incorporate both HEMT devices for
Low-Noise temperature performance and GaAs FET
devices for low intermodulation. The unit uses surface
mounted components for robotic manufacturing
techniques, thereby insuring maximum product
consistency and enhanced reliability.
The amplifier series (CLNA, KLNA, RCLNA, and RKLNA)
utilizes proprietary circuitry and high quality components
to achieve an MTBF 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).
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.
1+1 (one backup for one primary) and 1+2 (one backup for
two primary) redundant LNA systems are available,
complete with mounting plate, brackets and indoor
Redundancy Controller/Power Supply (transmit reject
filters, cables and other integration materials are offered
