Реферат: A mechanism for implementing a common carrier, multiple output RF unconverter including a method and apparatus for distributing the LO signals (LO-N) for both the first and second LO functions to several upconverter sections (13, 18), in plural channels, simultaneously. The technique eliminates the frequency synthesizers and VCOs typically required for each individual frequency converter section, thereby substantially reducing the board space and component count required to perform this function. By providing a distributed LO, only two LO synthesizers and VCOs (21, 23) are required per board, where a board might support anywhere from two to twelve upconverters (channel # N).
