Abstract :
The authors propose two configurations of fiber optic links for use in millimeter-wave subcarrier transmission for personal radio communication systems. The system concepts for millimeter-wave personal communication systems are first described and the advantages of millimeter-wave frequencies are discussed. The combination of direct modulation and indirect external modulation techniques was utilized to transmit 25-GHz FM and 70-MHz quadrature phase shift keying (QPSK) signals. The fiber optic link was experimentally investigated. The degradation caused by the insertion of the fiber optic link was not observed. The two signals were simultaneously transmitted and excellent performance was achieved.<>
