Abstract:
1. A transmitter configured to operate according to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 communications standard that does not interfere with a frequency generator that is configured to operate according to a Bluetooth communications standard, comprising: an oscillator configured to output a frequency signal characterized as having a first frequency, wherein the first frequency is outside of a frequency harmonic of the frequency generator that is configured to operate according to the Bluetooth communications standard; a first frequency divider, coupled to the oscillator, configured to divide the frequency signal by a divisor to produce a second frequency signal; a mixer, coupled to the oscillator and the frequency divider, configured to combine the first frequency signal and the second frequency signal to produce a mixed frequency signal; and a filter, coupled to the mixer, configured to filter the mixed frequency signal and to output a filtered frequency signal, wherein the divisor is selected based on a desired frequency value of the filtered frequency signal.
