<p>An apparatus selects CDMA (Code Division Multiple Access) reverse signals by adjusting CDMA reverse signals transmitted to an IF (Intermediate Frequency) board by means of a signal level converter having a plurality of level conversion devices, that is, by activating a level conversion device of a desired FA only and disabling other conversion devices to thereby receive signals of the corresponding FA and supply them to the modern chip. By doing so, the modern chip is capable of receiving the receiving signals of desired FA and demodulating them, and subsequently the apparatus can improve various utilizations of a System and selection in a usable FA when establishing the system.</p> |
