<P>PROBLEM TO BE SOLVED: To provide a high frequency module of a smaller size which is used for a communication device for a wireless LAN and can process transmission signals and reception signals of a plurality of frequency bands. <P>SOLUTION: A high frequency module 501 comprises: a switch circuit 10 connected to antennas; a diplexer 11 provided between first and second reception signal terminals and the switch circuit 10; and a diplexer 12 provided between first and second transmission signal terminals and the switch circuit 10. Each of the diplexers 11, 12 incorporates two band-pass filters formed by using a resonant circuit. The high frequency module 501 further comprises antennas inserted, respectively, between the first reception signal terminal and the diplexer 11, between the second reception signal terminal and the diplexer 11, between the first transmission signal terminal and the diplexer 12, and between the second transmission signal terminal and the diplexer 12. <P>COPYRIGHT: (C)2008,JPO&INPIT |
