| 摘要 |
The invention relates to a frequency divider ( 1 ), in particular for radio frequency (RF) applications, wherein the division ratio can be expressed by a-preferably odd numbered integer-divisor. The frequency divider ( 1 ) comprises an input circuit ( 10 ), which receives an input signal ( 5 ) as well as a first output signal ( 25 ). The input circuit ( 10 ) generates an intermediate signal ( 15 ), which has at least one main spectral component whose frequency corresponds to the sum or the difference of frequencies of said main spectral components of said input ( 5 ) and first output signal ( 25 ). Further, the frequency divider ( 1 ) of the invention has an output circuit ( 20 ), which receives said intermediate signal ( 15 ) and generates said first output signal ( 25 ). The main spectral component of said first output signal ( 25 ) has a frequency corresponding to the frequency of the main spectral component of said intermediate signal ( 15 ) divided by a-preferably even numbered integer. Particularly preferred this even number integer is 4.
