Abstract
A radio frequency, RF, switch device includes a plurality of switch units, wherein the switch units are coupled in series between a first series terminal and a second series terminal to establish a switchable RF path; and a plurality of ballasting capacitor units, wherein each ballasting capacitor unit is coupled in parallel to a respective switch unit, to provide a selectable capacitance in parallel to a signal path of the respective switch unit, wherein each ballasting capacitor unit includes at least one ballasting capacitor switch element to switch the capacitance of the ballasting capacitor unit between a first capacitance value and a second capacitance value, wherein the second capacitance value is larger than the first capacitance value.
