摘要： A Marchand balun circuit includes a Marchand balun, an unbalanced matching circuit, and a balanced matching circuit. The Marchand balun includes an unbalanced terminal, and two balanced terminals. The unbalanced matching circuit includes a first and the second impedances which are connected between the unbalanced terminal and ground in series, and a first resistor which is connected between ground and a connection node of the first and the second impedances. The balanced matching circuit includes a third and a fourth impedances which are connected between one balanced terminal and ground in series, a fifth and a sixth impedance which are connected between the other balanced terminal and ground in series, a second resistor which is connected between ground and a connection node of the third and the fourth impedances, and a third resistor which is connected between ground and a connection node of the fifth and the sixth impedances.
