1. An I/Q signal generating apparatus comprising:
a first resonance circuit including a first resistor, a first capacitor and a first inductor; and
a second resonance circuit including a second resistor, a second capacitor and a second inductor;
wherein
the first resistor is connected at one end to a first input terminal, and connected at another end to a first output terminal;
the second resistor is connected at one end to a second input terminal, and connected at another end to a second output terminal;
the first capacitor is connected to the one end of the first resistor and to the other end of the second resistor; and
the first inductor is connected to the other end of the first resistor and to the one end of the second resistor, crossing between the first resistor and the first capacitor.
