A communication system includes a transmitting device configured to transmit data and a receiving device configured to receive the data. The transmitting device includes first and second transmission lines and a differential signal outputter configured to generate differential signals from the microwave signal corresponding to the data, and to output one of the differential signals to the first transmission line and the other differential signal to the second transmission line. The receiving device includes third and fourth transmission lines and a converter. The differential signals are transmitted to the third and fourth transmission lines from the first and second transmission lines via line-to-line couplings. The converter then converts the differential signals into the microwave signal corresponding to the data, and outputs the converted microwave signal.

The present invention provides manganese-zinc-ferrite core fabrication process which can fabricate a manganese-zinc-ferrite core having high surface electrical resistance and low magnetic core losses without recourse to the introduction of nitrogen gas from the outside yet within a short time period, and such a manganese-zinc-ferrite core. To achieve this, manganese-zinc-ferrite core is formed into a given core shape. The core compact is fired in a firing atmosphere having an oxygen concentration controlled with carbonic acid gas and steam. Then, the compact is rapidly cooled at a cooling rate of 350&deg; C./hour to 850&deg; C./hour. In this way, a manganese-zinc-ferrite core is obtained.
