The LC-4000 series C-Band Low Noise Amplifiers are available in both single thread and redundant configurations. These LNA’s are specially designed for satellite earth station receiver front ends and other telecommunications applications. Utilizing state-of-the-art HEMT and GaAs FET technology, these amplifiers have been designed for both fixed and transportable applications. High performance models are available in several standard frequency ranges, with noise temperatures of 30, 35, 40 and 45 K. All noise temperature specifications are guaranteed over the full bandwidth of the LNA and are verified by cold load testing.

  • High output power, +20 dBm
  • Universal input ac power supply
  • Standard or extended band

Redundant LNA systems minimize system downtime due to LNA failure by providing a spare LNA and an automatic means of switching to the spare upon failure of a primary LNA. A 1:1 system provides one spare LNA for one primary LNA. A 1:2 system provides a spare LNA for either of two primary LNAs. The systems consist of an outdoor plate assembly which mounts at the antenna hub, an indoor control panel and interconnecting control cable.
