Abstract
Abstract – A novel self-heterodyne scheme was proposed, which transmitted both the RF1 and an additional carrier RF2 produced by an additional single-tone IF2. The feature of this scheme is that the frequency-fluctuation and the phase-noise generated in the local-oscillator of the transmitter can be eliminated, because the RF1 and the RF2 have both the frequency-fluctuation and the phase-noise in phase. It was reported that cost-effective 60-GHz modules with this scheme applied exhibited the phase-noise of -110 dBc/Hz at 100 kHz off-carrier frequency.
