ABSTRACT:
This optical receiver is capable of receiving broadband R-F modulated signals transmitted over fiber-optic cable. The receiver comprises a photodiode impedance matched to the input of an low noise, low distortion amplifier by an impedance matching transformer. A passive tuning network is placed between the photodiode and the transformer to improve the high frequency performance of the receiver. Distortion of the optical receiver is further reduced by cancelling even power distortion products from out of phase signals generated by the photodiode.
