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 1):
A radio frequency (RF) system with fast switching speed, the RF system comprising:\n an RF switch including a control input that controls an impedance of the RF switch; a switch bias circuit configured to receive a control signal for selectively controlling a state of the RF switch, the switch bias circuit including:\n a delay circuit configured to time a delay duration in response to a transition of the control signal; and \n a logic circuit configured to select a switch control voltage based on the control signal and configured to change the selection of the switch control voltage after the delay duration; and \n a resistor electrically connected between an output of the switch bias circuit and the control input to the RF switch, wherein the switch bias circuit is configured to pulse the switch control voltage in response to the transition of the control signal to thereby shorten a delay in switching the RF switch.
