A power distributing and synthesizing device which comprises first to third
signal terminals, first and second transmission lines and a resistor. The
first signal terminal is provided at the connection portion between one
end of the first transmission line and one end of the second transmission
line; the second signal terminal is provided at the other end of the first
transmission line; and the third signal terminal is provided at the other
end of the second transmission line. The resistor is connected between the
second signal terminal and the third signal terminal. LC serial resonators
each comprising an inductor and a capacitor are respectively connected
between the first to third signal terminals and a ground.
