Popis: We discuss collapse of the cross-spectrum phase noise measurement of thermally-limited oscillator due to anti-correlated thermal noise of the Wilkinson power splitter. We also examine effect of thermal noise of various resistive power splitters on such noise measurements. In addition, we introduce a novel technique to solve the cross-spectrum collapse.
