    • NY062 series Millimeter Wave Broadband Delay Line

    • Mainly composed of a high-power electro-optical conversion module, electro-optical modulation module, optical fiber delay module, photoelectric conversion module, delay control and visual touch screen system, network remote control system, RF input/output interface, and power supply system, etc.
    • The main function is to delay the millimeter wave signal received by the radar(The specific delay can be set on the touch screen) and then input it to the receiving system of the machine room.
    • Due to the natural ultra-strong anti-interference ability of optical fiber communication, it can avoid the interference of spatial leakage signals caused by traditional cable delays. Based on this anti-interference characteristic, the receiving system can obtain a reference signal that is closest to the radar-transmitted signal, thereby accurately calibrating the system.
    • Input signal: common ground radar pulse, continuous wave signal, pulse group, or pulse rapid frequency conversion signal.
