Abstract
A harmonic rejection mixer is disclosed that is capable of supporting wideband reception without any increase in circuit area. In this apparatus, transistors convert an RF signal to currents. Transistors perform frequency conversion based on the currents from the transistors and local oscillation signals. Transistors distribute the currents from the transistors to all transistors or some transistors based on a predetermined ratio. A load adds up the currents from the transistors and converts the resultant current to a voltage.
