Abstract

We have developed a 120-GHz-band wireless communication link that uses photonic and electronic technologies for the generation, modulation, and amplification of 125-GHz signals. Photonic technologies are suitable for generating ultra-high frequency signals, and enable long-distance wired transmission and the distribution of millimeter-wave signals. All-electronic systems, on the other hand, have the advantages of being compact and inexpensive, especially when the transceiver functions are implemented with monolithic microwave integrated circuits (MMICs). We succeeded in the error-free transmission of a 10-Gbit/s data signal over a distance of 450 m, and estimated the maximum transmission distance to be about 2 km.
