Abstract
A phase inverter includes a first transistor connected to a single signal port, a second transistor connected to the single signal port, a third transistor connected to a first power supply and forming a first contact point with the first transistor, a fourth transistor connected to the first power supply and forming a second contact point with the second transistor, and a transformer having a primary side connected to the first and the second contact point, and a secondary side connected to a first and a second differential signal port, wherein the phase inverter operates in one of a first phase mode in which only the first and the fourth transistor are turned on according to levels of voltages applied to gates of transistors, and a second phase mode in which only the second and the third transistor are turned on.
