PROBLEM TO BE SOLVED: To solve the problem that power is consumed in a strip isolation resistor pattern when a high frequency signal is applied to an input terminal. SOLUTION: The power distributor and combiner is provided with: a dielectric board 1; a ground conductor pattern 2a formed on one side of the dielectric board; an input line pattern 3 formed on the other side of the dielectric board; output line patterns 4a, 4b formed on the other side of the dielectric board; taper line type impedance transformer patterns 5a, 5b whose one-side end is connected to the input line pattern at a branch part and whose other end is connected to a plurality of output line patterns; and the strip isolation resistor pattern 8 placed between the adjacent taper line type impedance transformer patterns in a lattice form. Further, the interval of connection parts between the transformer patterns 5a, 5b and the resistor pattern 8 is increased more as the width of the transformer patterns 5a, 5b is narrower. Through the configuration above, the insertion loss of the power distributor and combiner can be reduced. COPYRIGHT: (C)2004,JPO
