Abstract:
An Interleaved Radio Frequency Digital-to-Analog Converter (RF DAC) suitable for use in cellular base stations and optimized to give both a wide RF tuning range and a wide RF bandwidth is disclosed. The RF DAC uses two levels of interleaving, the first providing a direct conversion path from Base Band (BB) to RF, and the second providing a variable interleaving factor through the use of summation to optimize the output bandwidth as a function of the RF center frequency. Digital Interpolation, including an arbitrary sample rate conversion filter, allows the RF DAC to operate from a wide range of possible BB sample rates and the DAC sample rate is a fixed ratio of the RF center frequency. As a result, the spurious outputs from the RF DAC are in known locations that are relatively easy to filter out, minimizing the frequency planning tasks required for a complete RF system design.

Claim (Index 14):
The system of  claim 6 , wherein the first data stream and the second data stream are a function, respectively, of an initial first data stream and an initial second data stream each having data points inter-spaced in accordance with a same baseband clock frequency, the system further comprising an interpolator to generate additional data points between the data points of the initial first data stream and between the data points of the initial second data stream, an inter-spacing between the additional data points being a function of a frequency of the local oscillator.
