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.

Claim (Index 13):
A radio frequency (RF) switching circuit comprising:\n a field-effect transistor (FET) switch including a gate; a switch bias circuit configured to receive a control signal and to output a switch control voltage; and a resistor configured to provide the switch control voltage to the gate of the FET switch, wherein the switch bias circuit is configured to generate a turn-on pulse of the switch control voltage in response to a transition of the control signal from an off state to an on state and to generate a turn-off pulse of the switch control voltage in response to a transition of the control signal from the on state to the off state, the switch bias circuit comprising:\n a delay circuit configured to time a delay duration when the control signal transitions; and \n a logic circuit configured to change the switch control voltage in response to a change in the control signal and configured to change the switch control voltage after the delay duration after the change in the control signal.
