- 1+1 and 1+2 Systems available
XLNA X-Band LNA Series
The Comtech EF Data (CEFD) Low-Noise Amplifier (LNA) series includes LNAs and redundant LNA systems (C-, X-, 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-, X-, 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 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, XLNA, 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 as required).
