Rp. Braun et al., OPTICAL HARMONIC UP-CONVERSION FOR MICROWAVE GENERATION IN BIDIRECTIONAL BROAD-BAND MOBILE COMMUNICATION-SYSTEM, Electronics Letters, 33(22), 1997, pp. 1884-1886
Two low phase noise microwave signals in the 18-20GHz band have been r
emotely generated for bidirectional 140Mbit/s OQPSK-transmissions by a
pplying a simple optical harmonic upconversion technique, One carrier
is modulated by the downlink data and the other one serves as local os
cillator signal for the uplink mixer in the base station.
