PURPOSE:To improve transmission characteristics at a high frequency band by performing susceptance matching on the ground side concerning reactance caused by a connection ribbon used for connecting two microwave integrated circuit boards at least. CONSTITUTION:When main line conductors 5 or the like of MIC boards 2 and 3 are connected by a connection ribbon 6, ground conductors 7 and 8 of the MIC boards 2 and 3 at the terminal parts of the two microwave integrated circuits are cut about for 1/8 wavelength, further, sub carriers 9 and 10 for fitting the MIC boards are also cut about for 1/8 wavelength at the junction part, and an impedance conversion part is provided to cancel the reactance of the connection ribbon 6. |
