OSCILLATOR CIRCUIT FOR RADIO FREQUENCY TRANSCEIVERS |
摘要 |
Oscillator circuit for radio frequency transceivers. An oscillator circuit includes a first oscillator that generates a signal having a first frequency and a second oscillator that generates a signal having a second frequency. The oscillator circuit includes a mixer that is responsive to the signal having the first frequency and the signal having the second frequency to provide a signal having a third frequency and one or more frequency components. The oscillator circuit includes a filter that is responsive to the signal from the mixer to attenuate the one or more frequency components and provide a signal having a desired frequency. The oscillator circuit includes a correction circuit to correct a drift in at least one of the first frequency and the second frequency by controlling the second frequency, thereby correcting the drift in the third frequency and the desired frequency.
