PURPOSE:To avoid the large sized connector and to avoid interruption of a signal at switching by connecting two coaxial connectors with a low loss transmission line and connecting the transmission line and a 3rd coaxial connector with a high impedance transmission line. CONSTITUTION:Two coaxial connectors 106 are fitted to a bottom side of a base 102 and a 3rd coaxial.connector 107 is fitted to an outer side of a vertical wall 103. A center conductor of the two connectors 106 is connected to a strip line 108a and extended via a chip resistor 109 having a comparatively high resistance and connected to a center conductor of the 3rd connector 107. Furthermore, the strip line 108b extended in crossing with the extended part is connected to a ground conductor via a chip resistor 110 having a comparatively low resistance. The impedance of the strip line is selected to be a desired impedance and the earth conductor of the strip line is connected to an outer conductor of the coaxial connector. Thus, a low loss line is used to interconnect the two connectors 106 and the connector 107 acts like a high impedance check terminal. |
