Abstract
An RF switching device having distributed shunt switches distributed along transmission lines to improve RF bandwidth as well as the signal isolation of the device. The shunt switches may be physically positioned on both sides of the transmission lines to keep an integrated circuit (IC) design essentially symmetrical so as to provide predictable and reliable operational characteristics. Some embodiments include stacked FET shunt switches and series switches to tolerate high voltages. In some embodiments, the gate resistor for each FET shunt switch is divided into two or more portions.
