Patent ID: 7786787

Claim:
An integrated circuit for selectively connecting and disconnecting a first RF signal port to a second RF signal port comprising: a signal path between the first RF port and the second RF signal port; at least one switching field effect transistor having a signal path coupled between the first RF signal port and the second RF signal port and a control electrode; a shunt transistor having a current path with a first end coupled directly to the control terminal of the at least one switching transistor without intervening elements and a second end coupled to a low impedance path to a ground reference for the signal path and a control electrode coupled to the ground reference through an impedance; and a control voltage having at least a first state and a second state for controlling an on/off state of the at least one switching transistor and the shunt transistor, the control voltage coupled to the control electrode of the at least one switching transistor and to the current path of the shunt transistor.
