PROBLEM TO BE SOLVED: To provide a power divider/combiner that is easy to manufacture and compact by dispensing with two shunt capacitances.SOLUTION: The power divider/combiner includes: a branch line circuit 1 in which four transmission lines 2a, 2b having an electrical length formed to less than a quarter wavelength about an operating center frequency are opposed and interconnected symmetrically with respect to two axes, and terminals are formed at respective connection points; series capacitances 3 formed between the respective connection points of the branch line circuit 1 and the corresponding terminals; and short circuit stubs 4 connected between the respective series capacitances 3 and the corresponding terminals, and having an electrical length formed to less than the quarter wavelength about the operating central frequency. Such a simple circuit configuration as is implemented with not two shunt capacitances but only the series capacitances 3 and the short circuit stubs 4 can implement ease of manufacture and compactness. |
