RADIO FREQUENCY SWITCHING CIRCUITRY WITH IMPROVED SWITCHING SPEED
First Claim
1. Radio frequency (RF) switching circuitry comprising:
- one or more RF switching elements coupled in series between a switch input node and a switch output node, wherein a state of the one or more RF switching elements is determined based on a control signal;
a control signal input node configured to receive the control signal;
a common resistor coupled between the control signal input node and the one or more RF switching elements; and
common resistor bypass circuitry configured to receive the control signal and bypass the common resistor for a predetermined time period following one or more of a leading edge of the control signal and a falling edge of the control signal.

Abstract
RF switching circuitry includes one or more RF switching elements, a control signal input node, a common resistor, and common resistor bypass circuitry. The one or more RF switching elements are coupled in series between a switch input node and a switch output node. A state of each one of the one or more switching elements is determined based on a control signal. The control signal input node is configured to receive the control signal. The common resistor is coupled between the control signal input node and the one or more RF switching elements. The common resistor bypass circuitry is configured to receive the switching control signal and bypass the common resistor for a predetermined time period following one or more of a leading edge of the switching control signal and a falling edge of the switching control signal.
