Abstract
Methods and systems for processing signals for a multiband radio are disclosed herein. Aspects of the method may comprise dividing an input signal generated by an oscillator used to generate signals for each of a plurality of bands for the multiband radio. A feedback loop reference signal may be generated from the input signal and a coarse calibration signal may be generated from the feedback loop reference signal. The oscillator may be calibrated utilizing the coarse calibration signal. The input signal may be buffered and/or divided by a divide by four (4) divider circuit. The input signal generated by the oscillator may be between about 3.4 GHz and 4 GHz. The generated feedback loop reference signal may be buffered and/or divided prior to the calibration. The coarse calibration signal may comprise a 7-bit calibration signal. A fine calibration signal may be generated from the feedback loop reference signal.
