PLL LNB with AGC L.O. 11.8

  • Description
  • Downloads

UMT presents new PLL LNB with AGC L.O. 11.8.

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.

PLL LNB with AGC L.O. 11.8 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. 

LO: 11.8 GHz | IN: 12.75 - 13.55 GHz | OUT: 950 - 1750 MHz
