As shown in a plan view and a front view, respectively, in b), various parts 20 are mounted on a partial area on one printed circuit board 10 to constitute a transmitter l, and in the same way, other areas of the printed circuit board 10 are mounted. The receiving section 2 is configured in the following. In this case, in the printed circuit board 10, various components are attached to one side of the board, and component leads protruding from the opposite side of the board are connected by soldering or the like.

る。In the above-mentioned wireless transceiver, since the transmitter 1 and the receiver 2 are integrally assembled on one printed circuit board IO, interference between transmission and reception is likely to occur due to a common current flowing to the ground. For this reason, the transmitter and receiver are isolated,
It is necessary to consider the arrangement of various parts so as to minimize mutual interference between the two. For example, in the example shown in FIG. 4, electromagnetic shielding is performed between the transmitting section and the receiving section at the position indicated by the chain line in the drawing to ensure isolation between the two.

Further, there is a problem that the transmitter/receiver tends to become large due to the addition of the electromagnetic shielding structure, and it is difficult to reduce the size of the transmitter/receiver.

The receiving section is constructed by soldering on the surfaces, and the soldering of each of these printed circuit boards is such that the two printed circuit boards are placed facing each other with their surfaces close to each other or in contact with each other.
