A frequency doubler includes a first Gilbert cell, a second Gilbert cell coupled to the first Gilbert cell, a frequency generator configured to apply a first sinusoidal wave to the first Gilbert cell, and a phase shifter applying a sinusoidal wave shifted from the first sinusoidal wave to the second Gilbert cell. A method of doubling frequency without using a feedback loop includes providing a first Gilbert cell, providing a second Gilbert cell coupled to the first Gilbert cell, applying a first sinusoidal wave to the first Gilbert cell, and applying a sinusoidal wave shifted from the first sinusoidal wave to the second Gilbert cell.
