Abstract:
1. A wireless transceiving apparatus for variability of signal processing band, comprising: an analog processor having a plurality of components on a path of transmission/reception signals, for performing analog signal processing, the components include at least one resonator; a digital processor for performing digital signal processing on an output signal of the analog processor or data to be transmitted to the analog processor; and a frequency synthesizer for providing anyone of a plurality of local oscillation (LO) frequencies among a signal processing band for tuning the analog processor at the provided LO frequency and for providing a resonator controlling signal to at least one resonator of the analog processor so as to vary tuning along the signal processing band of the analog processor when a different LO frequency is provided from the frequency synthesizer to the analog processor wherein the frequency synthesizer controls a frequency of a voltage controlled oscillator (VCO) and a resonance frequency of the signal processors to have a rational number ratio relative to the provided LO frequency, wherein the frequency synthesizer provides the resonator controlling signal to the VCO and to the analog processor, wherein the frequency synthesizer includes:
