Abstract
The invention provides a transceiver in which a mutual interference between the transmitting and receiving circuits can be suppressed, without a shielding plate therebetween. The transceiver comprises the first and second printed circuit boards, which are positioned face to face. Components of the transceiver are mounted on the front surfaces of the aforementioned printed circuit boards, and compose the transmitting and receiving circuits. The front surfaces of the first and second boards are respectively divided into the transmitting and receiving regions As and Bs, on which corresponding components are respectively mounted. The aforementioned regions As and Bs are so formed that they are respectively positioned face to face, then the components of the transmitting and receiving circuits are never positioned back to back, and the mutual interferences between the transmitting and receiving circuits does not occurs, even if a shielding plate is eliminated.
