Beschreibung
Zusammenfassung:	A switch arrangement comprising:a transceiver node coupled to a first and second circuit branch, the first circuit branch including a transmit node, the second circuit branch including a receive node;wherein the first circuit branch comprises an inductor coupled in series and a first semiconductor switch, in parallel, configured to provide a switched coupling to a reference voltage; andwherein the second circuit branch comprises one of:i) a second and third semiconductor switch; andii) a second semiconductor switch and a third semiconductor switch configured to control the application of a supply voltage to an amplifier; andiii) a further semiconductor switch configured to control the application of a bias current to an amplifier; whereinin the first switch mode, impedance matching between the transceiver node and transmit node is provided;in the second switch mode, impedance matching between the transceiver node and receive node is provided.
