A frequency multiplier oscillation circuit (and a method of multiplying a fundamental wave) includes an oscillation unit, a multiplication unit, and a fundamental wave component removal unit. The oscillation unit outputs a fundamental wave. The multiplication unit multiplies the fundamental wave to output the multiplied wave. The fundamental wave component removal unit cancels a fundamental wave component included in the multiplied wave based on the fundamental wave that is output from the oscillation unit to output the multiplied wave to an output terminal.
