This book explains concepts behind fractional subsampling-based
frequency synthesis that is re-shaping today's art in the field of
low-noise LO generation. It covers advanced material, giving clear
guidance for development of background-calibrated environments capable
of spur-free synthesis and wideband phase modulation. It further expands
the concepts into the field of subsampling polar transmission, where the
newly developed architecture enables unprecedented spectral efficiency
levels, unquestionably required by the upcoming generation of wireless
standards.
