Aspects of this disclosure relate tuning an impedance presented to a common port of a multi-throw switch. The impedance can be tuned based on an impedance associated with a throw of the multi-throw switch that is activated. This can, for example, provide impedance matching for a duplexer port coupled to a throw of the multi-throw switch that is activated. According to embodiments of this disclosure, a shunt inductor in parallel with a tunable capacitance circuit can tune the impedance presented to the common port of the multi-throw switch. The shunt inductor and the tunable capacitance circuit can be coupled to a node in a signal path between an antenna switch and an antenna port in some embodiments.
