Abstract:
A FET-based RF switch architecture and method that provides for independent control of FETs within component branches of a switching circuit. With independent control of branch FETs, every RF FET in an inactive branch that is in an “open” (capacitive) state can be shunted to RF ground and thus mitigate impedance mismatch effects. Providing a sufficiently low impedance to RF ground diminishes such negative effects and reduces the sensitivity of the switch circuit to non-matched impedances.

Claim (Index 10):
A switchable branch circuit including:\n (a) at least two switches each configured to be connected to respective external circuit elements; (b) a common node connected to and situated between the at least two switches; and (c) a settable shunt circuit, the shunt circuit including:\n (1) a first shunt circuit switch coupled to the common node; \n (2) a second shunt circuit switch coupled between the first shunt circuit switch and circuit ground; \n (3) a signal port coupled between the first and second shunt circuit switches and selectively connectable to at least one of the external circuit elements; and \n (4) an independent control circuit coupled to the first shunt circuit switch and configured to independently set a switching state for the first shunt circuit switch; \n wherein, within the switchable branch circuit:\n in a first inactive mode, the first and second shunt circuit switches are set to a closed state and the at least two switches are set to an open state so as to shunt the common node to circuit ground in order to improve isolation between any external circuit elements connected to the switches, and \n in an active mode, the first shunt switch circuit is set to a closed state, the second shunt circuit switch is set to an open state, and at least one switch is set to a closed state, so as to enable coupling of the signal port through the first shunt switch to the common node and to enable coupling of the common node through such at least one closed state switch to the respective external circuit elements connected to such at least one closed state switch.
