• 1 : 2 four-line transmission line transformer
• multimode feed network
• the analysis method of the asymmetrical bifilar even transmission line
• transmission-line equation

In this paper, by applying with the analysis method of the asymmetrical(current) bifilar even transmission line, the analysis for the characteristic of impedance converting, output balance and transmission of four-line transmission line transformer are done. The impedance theoretical result, which is better than the result by transmission equation especially in low frequency, is in good agreement with the metrical values. The analysis of magnetic core is simplified by transmission coefficient, but out with the equivalent circuit. This provides the elaborate foundation for the device, modeling and optimize of the multimode feed network.
