RADIO WAVE RECEPTION/OPTICAL TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radio wave reception/optical transmission system capable of performing sensing of a radio wave in the SHF band with high sensitivity.SOLUTION: A radio wave reception/optical transmission system 10A includes: an antenna 11 for receiving a radio wave in the SHF band; an amplifier 13 formed by a depression type transistor 23 for amplifying electric field intensity of an electric signal output from the antenna 11; a bias circuit 14 for applying given bias voltage to the transistor 23 to make the transistor 23 operate; a photoelectric conversion first element 15 for supplying a drive power source to the transistor 23; a photoelectric conversion element first light source 16 for emitting photoelectric conversion light to the photoelectric conversion first element 15; a photoelectric conversion second element 17 for separately supplying a bias power source to the bias circuit 14; and a photoelectric conversion element second light source 18 for emitting photoelectric conversion light to the photoelectric conversion second element 17.
