Abstract

PURPOSE:To obtain a transformer wherein higher region characteristics are greayly improved, and broad band is obtained by matching the impedance at input and output terminals of four pair-wire type coils having good characteristics with respect to a load. CONSTITUTION:One end of each coaxial cable is the input terminal and the other end thereof is the output terminal. The two pair-wire type coils 6, 7, 12, and 15 are pierced through a mangetic core 5, and the impedance coverting transformer is constituted by coaxial lines 4. Central conductor input terminals 8 and 9 for the coils 6 and 7 are connected, and a positive side input terminal 10 for the transformer is obtained. An outer input terminal 11 of the coil 7 and a central input terminal 13 of a coil 12 are connected. An outer input terminal 14 of the coil 12 and a central inoput terminal 16 of the coil 15 are connected. Outer input terminals 17 and 18 of the coil 6 and 15 are connected and negative input terminal 19 of the transformer is obtained. A central output terminal 20 of the coil 6 is made to be a positive output terminal 21 of the transformer. An outer terminal 22 of the coil 6 and central output terminals 23-25 of the coils 7, 12, and 15 are connected. Outer output terminals 26-28 are connected, and a negative output terminal 29 is obtained.
