Optical fiber link port extender for vector network analyzer

摘要

We have developed a microwave measurement system using optical fiber link transceivers for vector network analyzer (VNA). Our proposed system can extend the port of vector network analyzer using optical devices and optical fibers. Further, it can measure S-parameters in full 2-port calibration up to 4GHz. The dynamic range of S₂₁ is found to be more than 100 dB using direct access port of VNA.
