Abstract
An RF switch circuit is provided. The RF switch circuit may include a first switch disposed between a transmitting port and an antenna port and including a plurality of first transistors; a second switch disposed between the antenna port and a receiving port and including a plurality of second transistors; and a switch control circuit configured to generate control voltages to control the first transistors and the second transistors, generate a first Off voltage to turn off at least one first transistor among the plurality of first transistors and the plurality of second transistors in a transmitting mode, and generate a second Off voltage to turn off at least one second transistor among the plurality of first transistors and the plurality of second transistors in a receiving mode, wherein the second Off voltage may be higher than the first Off voltage.
