Abstract: A balun includes first to fourth lines and a stack. A plurality of first conductor layers forming the first and third lines are located in a first region in the stack. A plurality of second conductor layers forming the second and fourth lines are located in a second region in the stack. A ground conductor layer is located closer to the second region than to the first region. The plurality of second conductor layers include a conductor layer pair where a distance between two conductor layers is smallest.

Abstract: A directional coupler includes a first to a fourth port, a main line connecting the first port and the second port, a first and a second subline section configured to be electromagnetically coupled to the main line, and a phase shifter. The first subline section, the phase shifter, and the second subline section are arranged in this order in series between the third port and the fourth port. The phase shifter outputs a signal that is phase-delayed relative to an input signal. The phase delay amount of the output signal of the phase shifter relative to the input signal increases with increasing frequency of the input signal. A frequency twice as high as the frequency of the input signal at which the phase delay amount is 90 degrees is lower than the frequency of the input signal at which the phase delay amount is 180 degrees.

Abstract: A directional coupler includes: a first to a fourth port; a main line connecting the first and second ports; a first to a fourth subline section electromagnetically coupled to the main line; a first to a third matching section; and a stack. The first subline, first matching, third subline, third matching, fourth subline, second matching, and second subline sections are arranged in this order between the third and fourth port. The first and second matching sections include an inductor connecting two subline sections located on opposite sides of the matching section. Each of one or more conductor layers used to form the inductor includes two connection portions for electrical connection to respective other elements, and a line portion connecting the two connection portions. The inductor excluding the connection portions does not include portions that overlap each other when viewed in the stacking direction of the stack.
