Abstract
A radio frequency switching circuit may include a first switching circuit unit including first to n(n is a natural number greater than at least 2) transistors Mto Mn connected in series between a first signal port for transmission and reception of signals and a common connection node connected to an antenna port and operated according to a first gate signal; a second switching circuit unit connected in series between the common connection node and a second signal port for transmission and reception of signals and operated according to a second gate signal; and a first impedance adjuster forming an alternating current (AC) ground path between a ground and a gate of the first transistor of the first switching circuit unit when the first switching circuit unit is in an off-state.
