Abstract
The invention provides a mechanism for implementing a common carrier, multiple output RF upconverter. The preferred embodiment of the invention comprises a method and apparatus for distributing the LO signals for both the first and second LO functions to several upconverter sections simultaneously. This technique eliminates the frequency synthesizers and VCOs typically required for each individual upconverter 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 VCO's are required per board, where a board might support anywhere from two to twelve or more upconverters.
