Patent attributes
A Radio Frequency (RF) switch having two or more stages coupled in series is disclosed. A first Field-Effect Transistor (FET) with a first control terminal is coupled across a gate resistor to shunt the gate resistor when the first FET is on. An RF switching device is configured to pass an RF signal between a signal input and a signal output when the RF switching device is on. A second FET having a second control terminal coupled to an acceleration output is configured to shunt the RF switching device when the second FET is on. A third FET is coupled between the first control terminal and the signal input for controlling charge on a gate of the first FET. A third control terminal of the third FET is coupled to an acceleration input for controlling an on/off state of the third FET.
