Patent ID: 7852172

Claim:
A Radio Frequency (RF) switch, the RF switch comprising at least a first transistor and a second transistor, wherein the first transistor receives a first input signal and the second transistor receives a second input signal, the RF switch providing at least one output signal, the at least one output signal being based on conduction of one of the first input signal by the first transistor and conduction of the second input signal by the second transistor, the RF switch comprising: a. at least one first-biasing circuit, the at least one first-biasing circuit being connected to the first transistor, the at least one first-biasing circuit provides a first bias voltage at a gate terminal of the first transistor to increase conduction capability of the first transistor when the first transistor is in a conducting state and the second transistor is in a non-conducting state, wherein the at least one first-biasing circuit comprises: i. at least one of one or more first capacitors and one or more first resistors, wherein the one or more capacitors are connected to the first transistor and the one or more first resistors, the one or more first capacitors coupling the first input signal with the at least one first-biasing circuit; and ii. one or more first diode detectors; and b. at least one second-biasing circuit, the at least one second-biasing circuit being connected to the second transistor, the at least one second-biasing circuit provides a second bias voltage at a gate terminal of the second transistor to decrease conduction capability of the second transistor when the first transistor is in the conducting state and the second transistor is in the non-conducting state, wherein the at least one second-biasing circuit comprises: i. at least one of one or more second capacitors, one or more second resistors and one or more transistors; and ii. one or more second diode detectors, wherein the one or more second diode detectors are connected in series as a series-diode detector, the series-diode detector being connected to the one or more transistors and the one or more second capacitors.
