Trunk amplifiers TERRA , series DA213

3
Manufacturer:
Type of amplifier:
 

GaAs push-pull technology; changeable backward channel band owing to built in diplexer modules; built in interstage modules of attenuator and  line equalizer which improve amplifier technical specifications; damp-proof  shielded molded case; static power supply unit; protection against voltage surge at inputs and outputs; models with distant feed and mains supply.

Advantages:

  • GaAs push-pull technology;
  • Changeable backward channel band owing to built in diplexer modules;
  • Built in interstage modules of attenuator and line equalizer which improve amplifier technical specifications;
  • Damp-proof  shielded molded case;
  • Static power supply unit;
  • Protection against voltage surge at inputs and outputs.

You can familiarize yourself with the list of inserts in TERRA base amplifiers, series DA106, DA106Р, DA116, DA116Р and their technical specifications here.

* - frequency range depends on built in diplexer. 
** 36 ± 0.75 dB for amplifiers with built in module pf 01-12
All parameters are measured with pl 01-00 short-circuits, instead of backward channel diplexers, built in input demultiplier; pl 02-00 instead of built in line equalizer, output demultiplier, prime amplifier; JXP-0.
Output level (CTB, CSO, XMOD) is measured with an interstage line equalizer 6 dB.
