  • Flexibility is attained owing to built-in modules of the feedback channel: a passive module pd02-xx and
  • an active module pr02-xx;
  • Easily replaceable built-in modules without dismantling the amplifier; 
  • Built-in smooth controls over gain and gain slope;
  • A metal-plastic case for indoors installation;
  • A test point at the output and a safety-ground clip.


                mains supply


  • remote power supply; transfer of supply voltage to the output (switchable)

                 * depends on the module of feedback channel: a passive pd 02-xx or an active pr02-xx (the modules of feedback channel

                are delivered separately);

                 **  for amplifiers with feedback channel, it is  ± 0.7 dB;

                 *** with f>40 MHz, the reflection factor >14 dB (40 MHz) - 1.5 dB/octave, but no less than 10 dB.
