Art optical carrier generation approach is presented for cellular millimete
r-wave radio systems. The well-known methods distribute the millimeter wave
signal via fibers. They have drawbacks because they need very high-speed p
hotonic components that are expensive. This problem is over come by the new
approach utilizing an optically transmitted low-frequency reference signal
to generate the millimeter wave carrier. The new approach applies inexpens
ive photonic components and is less sensitive to the fiber dispersion.
