Product Details

LL-1500 series L-Band Low Noise Amplifiers are specially designed for satellite earth station receiver front ends and other telecommunications applications. Utilizing state-of-the-art HEMT and MMIC technology, these amplifiers have been designed for both fixed and transportable applications. High performance models are available with noise temperatures as low as 35 K. Noise temperature specifications are guaranteed over the full bandwidth of the LNA.

Features

  • State-of-the-art noise performance
  • HEMT/MMIC design
  • Internal regulator
  • Reverse polarity protection
  • High reliability
  • Fault alarm

Options

  • 50 or 60 dB gain

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

  • LL-1500 Series L-band Low Noise Amplifiers (LNAs)
  • High quality dual coaxial switches
  • Manual override
  • Output coaxial isolators standard
  • Input coupler, output coupler, 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
