<p>Disclosed is a communication apparatus having a small-scale circuit used for modulation. A common transmission image rejection mixer (56) supplies transmission modulation frequencies to a plurality of quadrature modulators (23) (G, D, P, W). Accordingly, it is unnecessary to prepare the transmission image rej ection mixer (56) for transmission signal types, makes it possible to prevent the circuit scale from increasing. <IMAGE></p> |
