摘要
A transformer (101) includes four terminals (N1 to N4), and parasitic resistances (109 and 110) are present in the transformer (101). A coupling capacitor (102) is provided between the terminals (N1 and N3), and a coupling capacitor (103) is provided between the terminals (N2 and N4). Shunt capacitors (104 to 107) are respectively provided between the respective terminals (N1 to N4) and a ground. Further, a phase shifter (112) is electrically connected to the terminal (N2), and a phase shifter (113) having a phase delay larger than that of the phase shifter (112) is connected to the terminal (N3).
