A frequency switch, in particular for use in a multibarrd/multistandard power amplifier module, comprising at least two output ports, a first output port being arranged within a first output path and a second output port being arranged within a second output path, said output ports being connected with an input port via said output paths, each output path being provided with at least one RF block, each RF-block comprising a capacitor, a switching element and a quaterwave section, wherein for each RF-block a predetermined frequency band is selected and the length of said quaterwave section is matched to said selected frequency band in order to block incoming signals in said selected frequency band if the switching element of the corresponding RF-block is switched on. Thus a frequency switch for usage with a multiband power amplifier can be realised which allows selection of different frequency bands with reduced power loss.
