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
