Top view
The SA-91L R70901 amplifier is designed for amplification of the first SAT IF and terrestrial DVB-T/Radio signals within SMATV systems built with 9-input multiswitches. It has 8 satellite inputs and DVB-T/Radio input and allows for equalization of the input signals.
The SA-91L R70901 amplifier has LTE filter for eliminating unwanted signals in 800 MHz band (791-862 MHz) coming from LTE services.
Key features
  • Amplification and equalization of SAT IF signals (8 polarization-band combinations)
  • Amplification of DVB-T/Radio signals
  • Blocking of LTE signals (signals above 790 MHz)
  • Built-in compensation of the increased loss of signals at higher frequencies in the distribution cables
  • Power supply for other system components: LNBs, multiswitches, DVB-T preamplifiers, other SAT amplifiers
  • Die-cast housing guarantying high screening efficiency (class A)
Thanks to the application of the SA-91L/91DL amplifiers, SMATV systems based on multiswitches can distribute signals to hundreds of outlets. The adjustment of the SAT IF and DVB-T (47-790 MHz) gain is made with dedicated switches. In comparison with potentiometers, this solution increases the stability of the adjustments. The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.
The device has push-pull amplifier in the terrestrial path and built-in switching-mode power supply. Aside from powering LNB and multiswitches, there is an option of supplying power to a DVB-T preamplifier (12 VDC).
