Harmonic suppressing local oscillator signal generation

A method, comprising:

• identifying a target harmonic of a first LO frequency that is likely to cause interference;
• generating an LO signal having the first LO frequency, wherein each period of the LO signal is characterized by a duty cycle portion having a duration that is less than the LO signal period, wherein each duty cycle portion is characterized by a pulse pattern comprising a series of least two pulses spaced apart by at least one gap having a gap duration, wherein the at least one gap is positioned such that the LO signal has no content at the target harmonic;
• and
• providing the LO signal to a mixer for shifting an information signal encoding communication data between a baseband frequency and an RF frequency.

Local oscillator (LO) signal circuitry for use in a transceiver, the LO signal circuitry configured to output an LO signal having an LO frequency, comprising:

• generation circuitry configured to:
• generate the LO signal, wherein each period of the LO signal is characterized by duty cycle portion having a pulse pattern and a gap duration, such that each duty cycle portion of the LO signal comprises two pulses spaced apart by a gap having the gap duration;
• and
• provide the LO signal to mixer circuitry configured to shift an information signal that encodes communication data to a desired frequency;
• and
• selection circuitry configured to:
• identify a target harmonic of the LO frequency that is likely to cause interference;
• select a pulse pattern and a gap duration based at least on the target harmonic;
• and
• control the generation circuitry based at least on the pulse pattern and gap duration to generate the LO signal.
