Abstract
A novel 9 GHB measurement system with thermal noise limited sensitivit y has been developed for studying the fluctuations in passive microwav e components. The noise floor of the measurement system is flat at off set frequencies above 1 kHz and equal to -193 dBc/Hz. The developed sy stem is capable of measuring the noise in the quietest microwave compo nents in real time. We discuss the results of phase and amplitude nois e measurements in precision voltage controlled phase shifters and atte nuators. The first reliable experimental evidences regarding the intri nsic flicker phase noise in microwave isolators are also presented.
