Abstract :
The work presented here is focused on analytical comparison of various methods of generating a low phase noise millimeter-wave local signal, from a frequency reference. Noise performance requirements of directly and externally modulated fiber optic distribution networks are considered. Four techniques of multiplication, phase-locked loop, injection locking, and injection locking with phase locked loop are compared in terms of system figures of merit.
