Provided is a power combiner having a sufficient heat-resistance property so as to deal with high power. The power combiner is characterized in that: the power combiner comprises a 90 degree hybrid circuit; the 90 degree hybrid circuit comprises first to fourth transmission lines and first to fourth ports; the first, second, third and fourth transmission lines are connected in the named order and in a loop shape; the first port is connected to the junction between the first and second transmission lines; the second port is connected to the junction between the second and third transmission lines; the third port is connected to the junction between the third and fourth transmission lines; the fourth port is connected to the junction between the fourth and first transmission lines; when the first port is used as an input port for a given frequency, one-half the power of a signal inputted to the first port is outputted at each of the second and third ports and none of that power is outputted at the fourth port; and the thickness of the 90 degree hybrid circuit is equal to or greater than 0.4 mm. |
