TFA1000E Preamplifier Module

Overview        TFA1000EThe preamplifier module is a high performance and high quality amplifier.Together with OPTIVO optical transmission platform rack and TPS1000E power supply, it constitutes a forward RF transmission system with excellent performance.It can be used to amplify digital TV signal, telephone voice signal and data transmission system. Features         Adopt high-performance gallium arsenide module,and has excellent CTB、CSO indexes;
        Real-time transmission of the amplifier operating status parameters to the platform and display them;
        Modular design, excellent heat dissipation performance;
        Gain adjustable, slope electronic control is adjustable, easy to debug;
        Excellent heat treatment ensures the long-term reliability of the equipment;
        Supports hot swap;
        The average power and total power of each channel can be displayed through the main control interface;
        The panel display output level supports slight adjustment according to the measured frequency point signal amplitude, which is convienent for debugging and management;
        The open network management interface meets the national standard of network management,Conforming to SCTE HMS network management standards, all locally monitored parameters can be remotely managed in real time.
        The downlink RF signal is amplified. Its built-in microprocessor monitors the amplifier operating status parameters and transmits them to the OPTIVO platform through the bus Technical Specifications
