LK-DS-LNF Low Noise Figure Fiber-optic Tranmission& Simulator (Customized)
- Low Noise Figure
- Ultra-wideband
- High saturation reception
- Miniaturization
- Wide temperature application
Product Description
LK-DS-LNF series represents a suite of low noise figure fiber-optic transmission and optical simulation systems that have elevated the quality metrics of noise coefficient through the implementation of cutting-edge microwave photonic technologies. These technologies include high power and stability DC light power control with Relative Intensity Noise (RIN) reduction, precise external modulator biasing at arbitrary points, and ultra-wideband reception with high saturation capabilities. Consequently, LK-DS-LNF series outperforms conventional fiber-optic delay lines and optical simulators by a significant margin of 10 to 20 dB in noise figure.
LK-DS-LNF series is extensively deployable for applications such as the reception of broadband high-sensitivity radar signals, radar signal simulation, electronic warfare, and electronic reconnaissance. These systems are tailored to meet specific customer requirements and are capable of operating effectively across the entire P to Ka frequency spectrum.
We are able to manufacture products with customized delay characteristics, structural configurations, and quality grade specifications to align with user demands.
