Abstract:
A device for switching a radio frequency (RF) signal includes two or more field-effect transistor (FET) unit cells in a stacked or chain topology, and gate or body node filtration circuitry that preserves RF equipotential nodes. The filtration circuitry may be capacitive or resistive-capacitive. The filtration circuitry may be included in each unit cell of the device or in a gate or body bias network that is common to all unit cells in the device.
