Narda-MITEQ
The 1:1, dual 1:1 and 1:2 redundant low-noise amplifier (LNA) systems are designed to ensure continuous operation without disruption of signal transmission.
A fault condition in the on-line LNA, or an operator generated command, will switch the standby LNA to the on-line position and remove the on-line LNA from the signal path.
The redundant LNA system consists of an outdoor amplifier/switch assembly which mounts at the antenna hub, rack- mounted indoor local control unit and interconnection control cable.
FEATURES
• Low amplifier noise temperature
• Fault tolerant design
• Fully redundant, hot-swappable power supplies
• Remote control via RS-485 or RS-422 user selectable
• Automatic/manual control from both local and remote mode
• Remote status
• Off-line input/output access
• Amplifier current fault detection
• Weather resistant amplifier/switch plate assembly
• Time-stamped alarm history
• Front panel LNA bias display
OPTIONS
• Remote RS-232, Ethernet or contact closure
• Transmit reject filter
• Internal noise source
• Input/output signal monitors
• Higher gain
• Increased output power
• Remote control unit

NOMENCLATURE FOR MODEL NUMBERS Low-noise amplifier system model numbers:Model number: LN (controller)-(frequency band abbreviation)-(amplifier noise temperature)Controller code: 1 = 1:1 Controller 2 = 1:2 Controller 3 = Dual 1:1 Controller
Please note that each low-noise amplifier system is supplied with: 1 Redundant amplifier/switch assembly 1 Local control and monitoring unit 1 100 foot interconnection control cable (other lengths optional)
Example: 1:1 system, 10.95 GHz to 12.75 GHz with 65 °K amplifier noise temperature: LN1-109128-65
Example: 1:2 system, 3.4 GHz to 4.2 GHz with 30 °K amplifier noise temperature: LN2-340420-30
Assembly enclosure option: To substitute a weather resistant enclosure for the standard weather resistant plate assembly add -W to end of part number. The weather resistant enclosure is recommended for mounting in a nonsheltered environment with direct rainfall.
Example: 1:2 system, 3.4 GHz to 4.2 GHz with 30 °K amplifier noise temperature in a weather resistant enclosure: LN2-340420-30-W
