AN RF FRONT END WITH REDUCED CARRIER LEAKAGE

摘要

A method and apparatus that provide a frequency conversion in a radio frequency front-end are disclosed, including a frequency divider (407) that divides an input signal frequency by a predetermined value to produce an output signal frequency (417); and a frequency mixer (405, 406) that mixes t he output signal frequency (417) with a carrier signal frequency to produce a converted signal frequency, which is substantially equal to a difference between the output signal frequency (417) and the carrier signal frequency. The predetermined value and the input signal frequency are selected such tha t the carrier signal frequency is not substantially equivalent to an integer multiple of the output signal frequency (417). The method and apparatus can be used in a wireless communication receiver including wireless communication systems and wireless LAN systems.
