GaAs FET demodulator and down-convertor for optical-microwave links
Abstract
A single-gate GaAs FET is utilized to simultaneously perform the photodetection and down-conversion functions of an optical-microwave link receiver, with the transistor supplying its own local oscillator signal through self-oscillation and harmonic generation. Operation up through 89 GHz is demonstrated.
