Abstract
A method and apparatus that provide a frequency conversion in a radio frequency front-end are disclosed, including a frequency divider that divides an input signal frequency by a predetermined value to produce an output signal frequency; and a frequency mixer that mixes the output signal frequency with a carrier signal frequency to produce a converted signal frequency, which is substantially equal to a difference between the output signal frequency and the carrier signal frequency. The predetermined value and the input signal frequency are selected such that the carrier signal frequency is not substantially equivalent to an integer multiple of the output signal frequency. The method and apparatus can be used in a wireless communication receiver including wireless communication systems and wireless LAN systems.
