<P>PROBLEM TO BE SOLVED: To provide a multicarrier transmitter which is immune to interference radio waves and moreover, which can make a circuit small-sized and miniaturize ICs. Ž<P>SOLUTION: A multicarrier transmitter is provided with a first SAW oscillation circuit 11 capable of obtaining an oscillation signal of a frequency f1; a second SAW oscillation circuit 12 capable of obtaining an oscillation signal of a frequency f2; a mixer 15 for combining the oscillation signals of the first and second SAW oscillation circuits 11, 12; and a selection output circuit 17 capable of selecting any one of these oscillation signals. The multicarrier transmitter is configured to transmit any one among frequencies f1, f2 and f3(f1+f2), while utilizing the oscillation signal. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
