| Abstract: | The power combiner/divider based on transmission line transformer is an ideal radio frequency device as its advantages: wide operating frequency band, high operating frequency, small device volume, hundreds watt of power capacity and small insert loss. This paper gives an analysis of the power combining/dividing and impedance matching circuit net, the two main parts of the power combiner/divider. Then, according to the transmission line transformer theory, different requirements are obtained for transmission line and magnetic core. An universal design method is summarized, which offers a theoretical reference to the design of power combiner/divider. |
