By using a special technique to produce very wide loop bandwidths in high-frequency PLLs, it’s possible to achieve very low phase noise rivaling that of direct (MMD) synthesizers, though with reduced size, weight, power, cost, and complexity.
A digitally calibrated, charge-pump phase-locked loop presented by imec at the recent ISSCC can generate high-quality FMCW signals for millimeter-wave radars with low power consumption.
A dual charge-pump structure combined with a dynamic loop-bandwidth technique serves to improve the phase-locking performance of a 1.4-to-1.6-GHz frequency synthesizer.
Compact and efficient, GUS350 power supplies use fanless conduction cooling, providing high efficiency, medical and industrial safety compliance, and flexible output options. Power your systems with confidence.
