Abstract
A radio frequency switch circuit includes: a radio frequency switch configured to control a radio frequency signal passing between a signal port and an antenna port; a first buffer configured to generate the first control voltage in response to a second control voltage; a second buffer configured to receive a third control voltage and configured to generate the second control voltage in response to the third control voltage; a first power supplier configured to supply a first high voltage to the first buffer and configured to supply a second high voltage to the second buffer; and a second power supplier configured to supply a first low voltage to the first buffer and configured to supply a second low voltage to the second buffer.
