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 ...
Saelig Company, Inc. has introduced the APSYN420B – an economical, wideband, fast-switching, low phase-noise 0.65GHz to 20 GHz frequency synthesizer with a remarkable resolution of 0.001Hz and phase ...
