<P>PROBLEM TO BE SOLVED: To provide a high frequency module which has a structure of transmitting and receiving three or more communication signals including two communication signals having approximate frequencies through a common antenna and which can transmit each communication signal with low loss. <P>SOLUTION: An individual terminal PIC13 of a switch IC11 is connected to SAW filters SAW1 and SAW3 whose pass bands are mutually spaced-apart. Between the individual terminal PIC13 and the SAW filter SAW1, a phase circuit of a low pass filter type comprised of an inductor LA and a capacitor CA is connected. An individual terminal PIC14 is connected to SAW filters SAW2 and SAW4 whose pass bands are mutually spaced-apart. Between the individual terminal PIC14 and the SAW filter SAW2, a phase circuit of a low pass filter type is connected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
