Abstract
A coupler circuit that includes two parallel coupled transmission lines (first transmission line and second transmission line) and a third transmission line, one end of the third transmission line connects to the end of first transmission line at one side, the other end of the third transmission line connects to the end of the second transmission line at the other side. Various coupling value and impedance transforming ratio can be achieved by select corresponding even and odd mode impedance of the coupled transmission lines and characteristic impedance of the crossing transmission line.
