ABSTRACT:
A triple band receiving terminal of a mobile communication system operates in three bands by installing an impedance matching unit and a band selection switching unit at the exterior of a dual band RF receiver. The triple band receiving terminal includes three filters for passing signals corresponding to three different bands, an impedance matching unit for matching impedance of signals passing the second and the third filters, and a RF (radio frequency) receiver for processing a signal inputted from the first filter and the switching unit as an intermediate frequency. Accordingly, by simplifying and minimizing the size of the construction of an internal circuit, a mobile communication terminal can be efficiently small size and light-weighed
