DTKom line broadband multiband amplifier

DTKom line broadband multiband amplifier

DTKom power-doubling dual-line broadband multiband amplifier

2 inputs: Return Ch./VHF/UHF/SAT1-SAT2

Very high power 2-input/2-output double line multiband amplifier for SMATV/CATV systems. One of the inputs covers the following bands: Return channel, VHF/UHF and SAT; the other allows the input of a second SAT. Each of the two outputs provides one of the satellites and the terrestrial bands + Return Ch. (5 MHz-30 MHz).

Highlights
  • Separate amplification minimizes intermodulation between bands and provides high output levels
  • Designed using Power Doubling technology, which guarantees levels in the 129 dBμV range for terrestrial signals.
  • Independent inputs for each satellite downlink (SAT)
  • Extracts MATV from one of the inputs and provides it on both outputs
  • SAT attenuation and equalization control on each input
  • MATV attenuation and equalization control.
  • Includes a high-performance low-power consumption switch-mode power supply
  • High-screening Zamak chassis The design facilitates appropriate cooling

Main features
  • Pre-equalization and equalization stages
  • Configurable gain for terrestrial band and return channel using two switches (high/low)
  • Intuitive front cover, including adjustments and block diagram
  • Output signal LED indicator
