Abstract
An apparatus for performing a frequency multiplication of an mm-wave wave signal is provided. The apparatus includes a first differential circuit that is capable of receiving a 0° phase component of an input signal and a 180° phase component of the input signal having a first frequency. The first differential circuit provides a first output signal that is twice the frequency and is in −phase(0°) based on the 0° the 180° phase components of the input signal. The apparatus also includes a second differential circuit that is capable of receiving a 90° phase component of the input signal and a 270° phase component of the input signal, and provide a first output signal that is twice the frequency and out of phase(180°). The apparatus also includes a differential transformer that is configured to receive the first output signal and the second output signal. The differential transformer is configured to provide a differential output signal that has a second frequency that is twice the first frequency.
