Abstract
A power radio frequency (RF) switch used in wireless communication is disclosed. A boosted switching control signal, which swings between a boosted supply voltage in which a system supply voltage is boosted and a negative supply voltage in which a polarity of the system supply voltage is inverted, is applied to a gate of a high-voltage transistor. Further, a substrate control signal which is synchronized with the boosted switching control signal, and swings between the negative supply voltage and a reference voltage may be applied to a substrate of the high-voltage transistor thereof.
