The R70501 SA-51 amplifier is designed for use in SMATV systems based on 5-input multiswitches. It has four satellite inputs and DVB-T/DAB/FM (Terr.TV) input. Placed on the input of the SMATV system, the device amplifies and equalizes the signals before further distribution.
Key features:
  • amplification and equalization of four SAT IF signals (polarization-band pairs),
  • amplification of DVB-T/DAB/FM signals,
  • compensation of coaxial cable attenuation,
  • power supply for other system components: LNBs, DVB-T preamplifiers, multiswitches, other amplifiers,
  • die-cast housing guarantying high screening efficiency (class A)
The use of SA-51/51D amplifiers allows for building large multiswitch systems distributing signals even to hundreds of subscriber outlets. The adjustment of the SAT IF and DVB-T/DAB/FM gain is made with dedicated switches. In comparison with potentiometers, this solution increases 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 option of supplying power to a DVB-T preamplifier (12 VDC).
