ABSTRACT:
Methods, circuits, and apparatus for providing an RF up-converter using digital circuits. One exemplary'embodiment provides an up-converter that uses multiple channels of parallel digital processing, then serializes individual bits from these channels to achieve higher frequencies. Specifically, I and Q components of a signal to be transmitted are decomposed into multiple components, each phase shifted from another. Quadrature versions of an oscillator signal are similarly decomposed and multiplied with corresponding I and Q signal components. The products are combined and serialized on a bit-by-bit basis to generate an RF signal.
