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.

Plate Assembly Features

  • LK-12000 Series Ku-band Low Noise Amplifiers (LNAs)
  • High quality dual waveguide/coaxial switches
  • Manual override
  • Waveguide input flanges
  • Output coaxial isolators standard
  • Transmit reject filter(s), input crossguide coupler(s), output coax couplers, and offline I/O options available

Redundancy Controller Features

  • 10/100 Base T Ethernet network interface
  • Supports SNMP v1, v2c, and v3
  • Rack-mount chassis, 19" wide, 1¾" (1 RU) high
  • Dual, redundant power supplies
  • Manual or automatic operation
  • Monitors unit currents, external alarms, or both
  • Automatically switches RF path to standby unit when unit failure occurs
  • User-selectable RS-232/-422/-485 serial I/O M&C interface
  • Parallel I/O M&C interface
  • Menu-driven user configuration of all options
  • Front panel graphically depicts switch positions and unit status
  • Worldwide universal AC input capability standard; consult factory for DC prime power
  • Audible alarm
  • CE certified and RoHS compliant; EAR 99
