Low noise amplifiers

Low noise amplifiers (LNA) by LLC SPC Communication-Service are provided for most used frequencies. LNA are designed for operation as a part of ground satellite stations and relay lines working in L, S, C, X, Ku and Ka ranges. Latest achievements in the field of semiconducting technology (HEMT and GaAs) are used in these LTAs to provide optimal characteristics and high level of reliability.

Standard characteristics

  • low coefficient of standing wave at input and output voltage;
  • sealed body;
  • proof from voltage fluctuations and transient process;
  • low noise temperature;
  • relay system of sending deficiency signals;

Extra potentialities

  • reservation 1:1, 1:2 and double reservation 1:1;
  • rejecting filter of transmitting signals;
  • power supply from a dc supply of 12V, 27V, 48V, 60V;
  • ingate availabilit.
