Advantages:

  • GaAs two-cycle output stage.
  • changeable backward channel band owing to built in diplexer modules.
  • built in interstage modules of attenuator and line equalizer that improve amplifier technical specifications;
  • built in inverted line equalizer;
  • dump-proof shielded molded case;
  • static power supply unit;
  • possibility of distant feed insertion into the line from the external power supply;
  • protection against voltage surge at inputs and outputs.

* - - frequency range depends on built in diplexer.  .

** - output level (CTB, CSO, XMOD) measured with an interstage line equalizer 6 dB.

*** - amplifiers are produced with F-connector contact socket or with carving aperture PG11.

- All parameters are measured with pl 01-00 short-circuits, instead of backward channel diplexers; pl 02-00 instead of built in output demultiplier, prime amplifier; JXP-0instead of input attenuator, line equalizer, inverted line equalizer, interstage attenuator and line equalizer.
