A one-chip integrated optical/RF transducer using a HEMT optomicrowave mixer and a slot antenna

摘要

In future mobile communications using fiber optic subcarrier transmission links, a large number of radio base stations with optical/RF transducers are required for radio signal transmission to the numerous mobile terminals. Therefore, it is very important to construct compact and cost-effective radio base station hardware. Accordingly, a simply optical/RF transducer MMIC using a HEMT optomicrowave mixer and a slot antenna is proposed and developed. It is confirmed that the MMIC has functions such as photodetector, optomicrowave mixer and radiator, i.e. it serves as an optical/RF transducer.
