PURPOSE: To obtain a balanced to unbalanced transformation circuit with a simple structure in which matching is facilitated even when characteristic impedances are largely different. CONSTITUTION: This circuit is composed of a balanced slot line 11 whose one- side end is branched into two 1st and 2nd directions, a 1st slot line 13 located in the 1st direction, a 2nd slot line 14 with a length whose difference of the length from the 1st slot line 13 is an add number multiple of a 1/2 wavelength with respect to a wavelength of a transmission signal and located in the 2nd direction, and an unbalanced couplanar line 12 whose center conductor is coupled with a slot conductor 15 between the 1st slot line 13 and the 2nd slot line 14 and which is coupled with ends of the 1st slot line 13 and the 2nd slot line 14. |
