Abstract
Disclosed are an apparatus and a method for switching RF signals. An RF switching apparatus according to an exemplary embodiment of the present invention includes: a plurality of FETs passing or blocking high-frequency signals depending on driving voltage applied to a gate; a control power supply generating control voltage for controlling the passing or blocking of the high-frequency signals; and a charge pump increasing the level of the control voltage and outputting the corresponding voltage as the driving voltage. According to the exemplary embodiment of the present invention, it is possible to minimize insertion loss generated in an RF switch.
