Abstract: Apparatus and methods for biasing radio frequency (RF) switches to achieve fast switching are disclosed herein. In certain configurations, a switch bias circuit generates a switch control voltage for turning on or off a switch that handles RF signals. The switch bias circuit provides the switch control voltage to a control input of the switch by way of a resistor. Additionally, the switch bias circuit pulses the switch control voltage when turning on or off the switch to thereby shorten switching time. Thus, the switch can be turned on or off quickly, which allows the switch to be available for use soon after the state of the switch has been changed.
