Typical Digital to Analog Converters (DACs) require a high-speed Master Clock to clock their digital filters and modulators, as well as some portions of their discrete time analog circuitry. This ...
RF absorption and PLL phase calibration help phased-array subsystems reduce clock spurs while preserving spectral purity and ...
This is Part 2 of a three-part series. As discussed in Part 1 and recapped here, modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher ...
The LTC6945 6-GHz integer-N PLL/synthesizer features –226dBc/Hz normalized closed-loop in-band phase noise, –274-dBc/Hz normalized in-band 1/f noise, –157-dBc/Hz wideband phase noise floor, and ...
A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...
