摘要：The present invention, generally speaking, provides for generation of at leastthree local oscillator signals for receiving a communication signal occupying
corresponding sub-bands of a frequency band using one or more frequency synthesizers(e.g., PLLs or the like) and one or more single sideband mixers. In accordance with certainembodiments, only one single sideband mixer is encountered along the output path of agiven local oscillator signal, thereby reducing spurs. In accordance with certain otherembodiments, three local oscillator signals are generated continuously.
