Abstract
A transmission apparatus for a CDMA communication system. The apparatus includes a multiplexer for multiplexing CDMA signals inputted through a plurality of channels, a voltage limiter for limiting a voltage of the multiplexed signal to a predetermined voltage level, an up-converter for up-converting the signal inputted from the voltage limiter into a high frequency signal, and a high power amplifier for amplifying the up-converted signal to a predetermined power level, for thereby decreasing an input voltage inputted into a high output amplifier, being used for a plurality of subscriber channels and using a low price high output amplifier.
