Abstract
An auxiliary voltage generating unit for a radio frequency switch includes a first input and a second input respectively configured to receive a first control signal and a second control signal, wherein the first control signal and the second control signal are configured to control which one of a plurality of paths in the radio frequency switch is enabled, and at least one output, configured to output an auxiliary voltage, derived from at least one of the first control signal or the second control signal, that is used to operate the radio frequency switch. The auxiliary voltage may be a bias voltage and/or a voltage used to power an inverter used to enable a selected branch as an isolation branch or shunt branch.
