<P>PROBLEM TO BE SOLVED: To provide a relatively compact RF line switching circuit having good transmission characteristics in which maintenance and repair are facilitated. <P>SOLUTION: The RF line switching circuit includes N/2 first RF transfer switches connected with N input lines, N/2 second RF transfer switches connected with N output lines, and N internal connection routes each consisting of an internal line or a combination of a plurality of third RF transfer switches and a plurality of internal lines. Each of the N input RF lines is connected with each of N output RF lines by switching the RF transfer switch on the route through a route consisting of the first and second RF transfer switches and the internal connection route. <P>COPYRIGHT: (C)2009,JPO&INPIT |
