PROBLEM TO BE SOLVED: To provide a communication device which has the scale of a circuit used for modulation being small. SOLUTION: The supply source which supplies modulation frequencies for transmission to orthogonal modulation parts 23 (G, D, P, W) is a common image removal mixer part 56 for transmission. Consequently, the circuit scale can be prevented from increasing, without having prepare to the image removal mixer part 56 for transmission for each kind of transmission signal. |
