—This paper reviews several techniques used to reduce the in-band phase noise contribution of 16 fractional-N frequency synthesizers. The paper develops several practical techniques for specifying the noise and linearity of components used in a 16 fractional-N synthesizer. As an example, it presents a synthesizer with an in-band phase noise floor of 97(More)
— A technique of spread-spectrum transmission, interpolated frequency-hopping (IFH), is presented. IFH employs a carrier that moves smoothly and continuously in frequency, helping to alleviate problems, such as spectral splatter and transient mismatch, which are a concern in conventional phase-locked loop (PLL)-based frequency-hopping spread-spectrum(More)
