    • PROBLEM TO BE SOLVED: To obtain a directional coupler which can increase a coupling degree without narrowing a coupling line interval even when another component is not added. SOLUTION: The directional coupler is provided with: a first transmission line 2 with an electric length of 1/4 wave length at a center frequency of a predetermined frequency band; a second transmission line 3 which is arranged facing the first transmission line 2, and has an electric length of the 1/4 wave length at the center frequency; a first capacitive reactance 6 which is formed so as to be connected in parallel to the first transmission line 2; and a second capacitive reactance 8 which is formed so as to be connected in parallel to the second transmission line 3.

    • PROBLEM TO BE SOLVED: To provide a waveguide type high frequency line which is small and has a function of converting a signal into a pair of differential signals and for output of the converted signals.
      SOLUTION: The waveguide type high frequency line includes a first section 41 divided into first and second waveguides 41a, 41b by a first dividing wall, a second section 42 configuring one waveguide, a third section 43 divided into third and fourth waveguides 43a, 43b by a second dividing wall, a fourth section 44 configuring one waveguide, and a fifth section 45 divided into fifth and sixth waveguides 45a, 45b by a third dividing wall. The first and second waveguides 41a, 41b have the same amount of phase shift mutually, the third and fourth waveguides 43a, 43b have a phase shift difference of 90°, and the fourth 44 section has a difference of 90° between an amount of phase shift of a high frequency signal passing in TE10 mode and an amount of phase shift of a high frequency signal passing in a TE20 mode.
