Zusammenfassung:Provided herein are oscillator paths between an oscillator and mixers. In an embodiment, the oscillator paths include a first path between an oscillator and a first mixer and a second pathbetween the oscillator and the second mixer, in which the first path is enabled in a first state (e.g., a low band state) and the second path is enabled in a second state (e.g., a high band state). The first path can include a radio frequency divider configured to receive a signal having the oscillator frequency and to divide the signal in frequency by a positive odd integer divisor greater than one, and a duty cycle correction circuit configured to receive an output from the radio frequency divider and provide an output having a duty cycle that is closer to 50% than the output from the divider. Such separate oscillator paths can, for example, enhance receiver performance.
