Abstract
This paper presents an analysis of the local oscillator noise reduction mechanism in transposed gain oscillators. The transposed gain oscillator is used for low phase noise signal generation. The results of the analysis show that the degree of LO noise reduction depends solely on the delay mismatch between the low frequency and local oscillator signal paths and that these delays also determine for which of the output frequencies the sideband noise is suppressed.
