ABSTRACT:
A switch includes at least two signal ports in series with a series FET connected therebetween, and a shunt path having an FET, whereby an input bias is applied to a gate on the series FET and to a drain on the shunt FET. In one embodiment, the switch includes a control signal input, an FET connected in series across the first port and the second port, the series FET having a gate coupled to the control signal input, and a shunt path provided by an FET, the shunt FET having a drain coupled to the control signal input and to the gate of the series FET, whereby a single control signal is applied to both the series FET and the shunt FET, via the control signal input, in order to turn the series FET on and simultaneously turn the shunt FET off and, conversely, in order to turn the series FET off and simultaneously turn the shunt FET on.
