Abstract
A circuit arrangement and a method of operating a circuit arrangement. The circuit arrangement includes an amplifier having an output port, a duplexer having an input port coupled to the output port of the amplifier and having a combined input/output port to couple to an antenna, and a switch configured to create an impedance load mismatch at the input port of the duplexer independent of the impedance of the output port of the amplifier by acting on a connecting line between the output port of the amplifier and the input port of the duplexer.
