Benefits:
- A plug-in module of the equalizer makes it possible to use this amplifier in narrowband networks; in shifting to broad band
- networks it is suffice just to replace modules of the equalizer;
- The both equalizers are delivered in set with the amplifier. A filter that improves the amplitude-frequency response of the
- amplifier at 300 MHz is replaced by a jump while operating at 862 MHz ;
- Flexibility in interactive networks is provided by various built-in modules of feedback channel: passive modules RP 30-01
- Built-in modules are easily replaceable without dismantling the amplifier;
- Delivered with built-in contact-makers;
- A push-pull output stage;
- Smooth control over gain and gain slope;
- A metal-plastic case for indoors installation;
- A test point at the output and a safety-ground clip.
