Circuit arrangement with an antenna switch and a bandstop filter and corresponding method

摘要

Implementations are presented herein that include an antenna switch that includes a plurality of ports. A bandstop filter is coupled to at least one of the plurality of ports of the antenna switch and the bandstop filter is configured to attenuate a disturbing frequency. A transistor is configured to receive a control signal and to switch on the bandstop filter responsive to the control signal.
