Abstract:

A differential amplifier for gigahertz bandwidth electrical signals using fiber optics and integrated optical devices has a differential gain which is a function of the electrical to optical and optical to electrical conversion factors. The common mode rejection ratio of the differential amplifier at 1 GHz was greater than 30 dB and the common mode rejection ratio depended on the time difference between the differential amplifier inputs. A differential amplifier fabricated in accordance with this inventive concept could be used as an integrated module in radar and communications systems.
