PURPOSE:To obtain the power distributing circuit capable of distributing electric power equally into four by using two Wilkinson type two-distributing circuits, and connecting input terminals of the Wilkinson type two-distributing circuits mutually and also connecting center parts of resistances to each other through a thin metallic wire. CONSTITUTION:The input terminals of the Wilkinson type two-distributing circuits 14 and 15 are connected to an input terminal 16 through connection lines 11 and 12 respectively. Metallic islands 21 and 22 are provided to the center parts of the resistances 9 and 10, and connected mutually through the thin metallic wire 23. When the lengths of the connection lines 11 and 12 and thin metallic wire 23 are set much shorter than wavelength, an equivalent circuit in a figure (a) is as shown in a figure (b). This equivalent circuit is equal to an equivalent circuit of a Wilkinson type four-distributing circuit. Consequently, a microwave inputted from the input terminal 16 is distributed equally as four waves to output terminals 17-20, which are isolated from one another. This circuit has conventional functions and is reduced in constitution size because it is composed of the two Wilkinson type two-distributing circuits.
