Double-frequency power divider and design method thereof

The invention relates to a double-frequency power divider and a design method thereof. The double-frequency power divider comprises three ports, six branch transmission lines, a short circuit branch knot, an open circuit branch knot and two earthing isolating resistors. The double-frequency power divider provided by the invention can realize any double frequency, any power distribution ratio, power distribution and composition of any resistive load, and overcomes the defects that the traditional Gysel type power divider only can carry out odd-time frequency doubling operation, equipower distribution, and equal port load; the double-frequency power divider is simple and compact in double-frequency working, the design is simple, the adjustable ranges of transmission line characteristic resistance and the resistor value dynamic state of each isolating resistor are large, the standard resistor value is conveniently taken and the microstrip line process has a requirement of the transmission line characteristic resistance to be realized; and the double frequency characteristic is obtained, simultaneously, the high power application of the Gysel type traditional power divider is reserved, and the double-frequency power divider is particularly suitable for microwave double frequency and high power distribution composition application.
