Abstract
A subharmonic mixer, including an amplification unit for amplifying an input signal using at least one pair of amplification devices connected in parallel and a mixing unit for mixing the amplified signal with local oscillation signals from local oscillators is provided. The mixing unit performs switching over the amplification devices and at least four pairs of switching devices connected in parallel with each other, two pairs of switching devices being connected in parallel with each other and performing switching over one amplification device. The switching devices are supplied with local oscillation signals having different phases respectively, and two switching devices forming a pair are connected in parallel with each other and supplied with local oscillation signals having a 180° phase difference therebetween. Accordingly, the switching stage is formed with one stage, the operation is enabled with low-voltage power supplies, and noise performance, linearity, and gain are enhanced.
