Abstract: The present invention provides a switchable wide band receiver front end device for a multiband receiver which includes a broadcast signal receiver (1) for receiving broadcast signals within multiple receiving frequency bands, which are divided into channels; a wideband low noise amplifier (2) connected to the broadcast signal receiver (1) for amplifying the broadcast signals of all frequency bands and for outputting amplified output signals which are branched to multiple switches (11, 12, 13) of a switching device (10), wherein the number of switches (11, 12, 13) corresponds to a total number of receiving frequency bands; multiple filters (22, 23, 24) each connected to a respective switch (11, 12, 13), wherein each filter passes all signals within an associated receiving frequency band; a mixer (30) connected to the output side of each filter for mixing the filtered signals with a locally generated mixing signal from a frequency synthesizer to produce intermediate frequency signals; and a controller (14) for

Abstract: The mobile phone is equipped for at least two frequency bands and includes an antenna coupled to a multiplex type filter. The multiplex type filter contains at least two disparate bandpass filters for separate reception or transmission frequency bands. A first bandpass filter of the at least two disparate bandpass filters has as a passband a first frequency band. A second bandpass filter of the at least two disparate bandpass filters has as a passband a second frequency band.
