Analog Video Splitter by ITL "Spectrum"
Analog Video Splitter 1→3 (Active) based on BC817
Manufacturer: ITL «Spectrum»
Main Description
The active analog video splitter from ITL «Spectrum» is designed to distribute a single composite analog video signal to three independent parallel outputs without signal level degradation. The device is built on the BC817 bipolar NPN transistor, ensuring stable operation at 5V power supply and low power consumption.
The splitter supports the standard 75-ohm video path, making it compatible with FPV cameras, analog video transmitters (VTX), digital video recorders (DVR), OSD modules, and other composite video (CVBS) devices. The 1:1 voltage gain ensures signal amplitude preservation without overloading receivers.
The active circuit avoids typical problems of passive splitters — signal level drop, contrast degradation, and interference when connecting multiple consumers. Compact dimensions and low weight make the module suitable for installation on UAVs, ground stations, or video labs.
