12-channel combiner-equalizer of UMT production is active device specially designed to combine 12 independent IF carriers (L-band, frequency range of 950-2150 MHz) with power adjustment and AGC for each channel.

12-channel combiner equalizer - principle of operation

Key features:

  • AGC
  • manual power adjustment
  • high output power linearity
  • low intermodulation distortions
  • small non-uniformity of a group delay
  • high output signal stability
  • 24/7

12-channel combiner-equalizer has 12 RF inputs for 12 IF carriers and 1 or 2 independent outputs. All inputs and outputs work in L-band. 1st output contains full spectrum combined from 12 inputs and is used for further signal transmitting. The 2d output is used for signal controlling (can be added by request) and has up to 30 dB lower signal power than the 1st input.

12-channel combiner-equalizer can be used in MVDS head-end, professional TV link and TV repeater stations due to its features such as automatic gain control (AGC) which provides high stability of output RF-signal power. The case of the 12-channel combiner-equalizer is designed for using in standard 19″ rack.
