UMT presents new Ku-band PLL LNB with AGC .

It is professional LNB which has the following advantages comparing with old one: wide dynamic range - up to 50 dB (biggest among any other LNB). AGC range: 25 dB, LO instability: 50 kHz, Gain (min): 40 dB.

Ku-band PLL LNB with AGC is professional low noise block down converter with automatic gain control designed for MVDS / MITRIS TV broadcasting systems (links and repeaters) application in which the signal stability is very important. In addition, PLL LNB with AGC has wide dynamic range (power at the input) which is the biggest among other LNBs. 

New PLL LNB with AGC has the following advantages comparing with old one: 

  • higher level stability
  • higher frequency stability
  • wider dynamic range - up to 50 dB (biggest among any other LNB)
  • less weight and dimensions
  • less price

 Output frequency range: 950 - 1950 MHz


  • Wide dynamic range (power at the input) - up to 50 dB (biggest among any other LNB)
