摘要: The present invention relates to a transceiver device having a switching arrangement and to a method of improving such a switching arrangement, wherein an input impedance of a duplexer means, as seen by a switching means (10) at a predetermined frequency, is transformed to a predetermined maximum or a minimum value. The switching means is used to selectively connect an antenna port to a transmitting and receiving path which leads to the duplexer means (14). The transformation of the input impedance can be achieved by providing a phase shifter (20) between a switching means (10) and the duplexer means (14). Thereby, the phase of the impedance can be optimized for minimal intermodulation distortion and to relax switch linearity requirements, so that the switching means (10) can be used for switching duplex signals.
