To realize a cost-effective and practical antenna base station CBS) for 60-
GHz-band millimeter-wave fiber-radio access systems, an approach to a singl
e optical component BS is presented in this paper. The external modulation
technique will allow to replace the pair of a photodetector (PD) and a lase
r diode with an external modulator at the BS by an optical transceiver. Two
system architectures using different types of optical transceivers are stu
died in detail: one employs an electroabsorption transceiver (EAT), and the
other employs an electroabsorption transceiver/mixer (EATX), The EAT serve
s simultaneously as a PD and an external light modulator in 60-GHz-band mil
limeter-wave region. The EATX furthermore acts as an IF-to-RE upconverter a
nd an RE-to-IF downconverter, It will be shown that both system architectur
es have good prospects to realize cost-effective fiber-radio access systems
