LNA Low Noise Amplifier

Our Low-Noise Amplifier (LNA) series includes LNAs and redundant LNA/LNB 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 redundant LNA/LNB systems include primary and backup LNA(B)s and an automatic switching controller. In case of primary LNA/LNB failure, fast automatic switchover to the backup LNA/LNB minimizes “down” time.


The amplifiers incorporate both HEMT devices for low-noise temperature performance and GaAs FET devices for low intermodulation.
The units use surface mounted components for robotic manufacturing techniques, thereby insuring maximum product consistency and
enhanced reliability. XLNA includes integrated filtering to address adjacent power issues peculiar to demanding X-Band terminals.


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 are housed in waterproof enclosures with 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 and LNB systems are available (refer to DST
datasheet for available LNBs), complete with mounting plate, brackets and indoor Redundancy Controller/Power Supply (transmit reject
filters, cables and other integration materials are offered as required).
