    • Description

    Features:

    • Large range of input optical power;
    • High sensitivity;
    • Duple GaAs RF amplifier technology with minimization of the level of products of the second and third order;
    • Built-in interstage attenuator;
    • Built-in interstage electronic equalizer allows you to refuse additional, replaceable modules;
    • Two RF outputs with the possibility of installing interchangeable inserts of the divider or couplers;
    • Change of the reverse channel band due to replaceable inserts of diplex filters;
    • Embedded module of the optical transmitter of the return channel;
    • Thermal stabilization of the output optical power of the transmitter;
    • Power supply unit from AC or DC;
    • By switching fuses, in the main power circuit, you can select the desired power supply method (from one of the outputs);
    • On the output and in the return channel of the unit there are control connectors for connection of measuring devices;
    • Additional input for summing RF signals of the 5-200 MHz range with the return channel signals;
    • Protection of RF amplifier output from high voltages;
    • Protection of the output stage of the RF amplifier from overload and unbalanced load;
    • Cast aluminum housing.
