EVALUATION OF TWO NON-STANDARD TECHNIQUES FOR THE PHASE NOISE CHARACTERIZATION AT MICROWAVE FREQUENCIES

摘要

Two different phase noise measurement techniques dedicated to the test of microwave free running oscillators are described and compared. The interest of an injection locking technique for the character.zation of the close to carrier performance of Iow phase noise DRO is shown through different measurements examples on state-of-the-art DRO at C and X band.
