Abstract

A filter stage for use in a receiver includes a switch with an input coupled to an antenna terminal, a first output and a second output; a first filter of a first type coupled to the first output; and a second filter of a second type different from the first type, coupled to the second output. A receiver includes a filter stage as mentioned above; and a switching unit coupled to the filter stage for controlling a switching state of the switch, to selectively connect the antenna terminal to the second output, depending on a selection signal.
