A system and method for processing signals in a mobile terminal routes received signals to signal processing units based on the bands in which the signals are located. Routing is preferably performed by a m-pole/n-throw electric switch where m.gtoreq.1 and n.gtoreq.1. The signal processing units may process signals in, for example, the DCN, PCS and GPS bands although other bands are possible. By using an electric switch instead of, for example, a diplexer circuit, the system and method significantly reduces insertion loss while simultaneously increasing the degree of isolation among the different bands of the received signals. Optimal receiver sensitivity is also achieved in each respective band.
