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 ...
At the heart of a transceiver is usually a phase-locked-loop (PLL) synthesizer, which delivers a signal to downstream components such as mixers, filters and power amplifiers. At higher frequencies, ...
This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...
