Radio-frequency (RF) switch circuits are disclosed providing uniform voltage swing across a transmit switch for improved device performance. A switching circuit includes a switch having field effect transistors (FETs) defining an RF signal path between the input port and the output port, the switch configured to be capable of being in a first state corresponding to the input and output ports being electrically connected so as to allow passage of the RF signal therebetween, and a second state corresponding to the input and output ports being electrically isolated. The switching circuit includes a voltage distribution circuit configured to reduce voltage distribution variation across the switch, including one or more elements coupled to a selected body node of one or more FETs so as to reduce voltage distribution variation across the switch when the switch is in the first state and encountered by an RF signal at the input port.
