Abstract
Radio frequency switch circuitry is disclosed having first and second port terminals, a switch branch having first and second branch terminals, and a branch control terminal, wherein the switch branch is configured to pass an RF signal between the first and second branch terminals in an on-state and block the RF signal from passing between the first and second branch terminals in an off-state in response to a control signal that is coupled with the RF signal and received at the first port terminal. Control signal decoupling circuitry has a control signal input terminal coupled to the first port terminal to receive the control signal coupled to the RF signal and a control signal output terminal coupled to the branch control terminal, wherein the control signal decoupling circuitry is configured to decouple the control signal from the RF signal and provide the control signal to the branch control terminal.
