Summary:Provided is an apparatus for sharing specific functions in a portable terminal capable of selectively using one of a CDMA communication system and a JCDMA communication system. The portable terminal includes a first switch unit and a second switch unit. The first switch unit selectively separates one of a CDMA RX signal and a JCDMA RX signal from a signal received through an antenna and outputs the separated signal to a low-noise amplifier. The second switch unit separates a frequency band of the selected communication system from an output signal of the LNA to select a specific-band signal and outputs the specific-band signal to a mixer.
