Optical fiber link antenna and EMI measurement system using optical biased devises

We propose an optical fiber link antenna and electromagnetic interference measurement system that consists of a receiving optical fiber link system, and a RF amplifier with photovoltaic power converter. Our proposed optical receiving system can measure less than -100 dBm input level from 1 GHz to 6 GHz. Our proposed transmitting optical system can radiate more than -20 dBm RF output level from 1 GHz to 6 GHz [1]. It is proved that our proposed optical system can be used to evaluate the antenna measurement with more than 100 dB dynamic range. Our proposed system can use radiated electromagnetic interference measurement over 1 GHz without metal cables.
