Abstract

An antenna multiplexer with a pi-network circuit is described, having an inductance connected in series and, on each of the two connection sides of the inductance, a capacitance connected in parallel. The pi-network circuit is used for effecting an impedance mismatch of a signal path of the antenna multiplexer.
