<p>Disclosed herein is a harmonic suppression circuit having a first microstrip line (3) and a second microstrip line (4) each having the same characteristic impedance. One end of the first microchip line is electrically connected to a transmission line (2) over which a signal having a predetermined frequency is transmitted, and one end of the second microstrip line is grounded. The length of the first microstrip line and the length of the second microstrip line are respectively set to the length corresponding to 1/8 of the wavelength with respect to the predetermined frequency. Series impedance means (7) comprised of capacitance means (5) and inductance means (6) is electrically connected between the other end of the first microstrip line and the other end of the second microstrip line. The reactance of the inductance means at the predetermined frequency are respectively set to 3/4 of the characteristic impedance of each microstrip line. <IMAGE></p> |
