Norwood, Mass. — Three phase-locked-loop (PLL) frequency synthesizers have been unleashed for the upconversion and downconversion of RF signals and for timing generation. The first synthesizer, the ...
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 ...
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 ...
