<p><P>PROBLEM TO BE SOLVED: To fully secure isolation between RF connectors while narrowing down an interval of the RF connectors in a radio part. <P>SOLUTION: In structure of the radio part consisting of a receiving system and a transmitting system for fixing a seating 2 as a heat sink to a printed circuit board 1 and covering the circuit side of the printed circuit board 1 by a shield case 3, a plurality of RF connectors 4 are provided, the RF connectors 4 are installed on a front surface part 2a of the seating 2, its dielectric 4b (Fig. 2(b)) is connected with a circuit of the printed circuit board 1 in the shield case 3 by passing between the front surface part 2a of the seating 2 and a front surface part 3a of the shield case 3 and the RF signals flow in the dielectric 4b. Then, shielding members 5 are provided by every RF connector 4, respectively so as to cover the dielectric 4b at a gap between the front surface parts 2a, 3a. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
