<p>A multi-band transmitting/receiving apparatus is provided to reduce a unit cost of a product and to improve the reliability of the product by providing a single local oscillation frequency signal to each converter from a distributor. An oscillator(51) generates a certain single reference frequency signal. A frequency synthesizer(52) outputs a certain local oscillation frequency signal with the single reference frequency signal generated from the oscillator(51). A distributor(53) includes a plurality of input/output units for distributing the local oscillation frequency signal uniformly. A plurality of multi-band processing units(54) receive local oscillation frequency signals outputted from the plurality of output units of the distributor(53), and output certain variable frequency signal.</p> |
