Abstract
Disclosed is radio frequency switch circuitry that includes a switch branch having a first branch terminal coupled to a first signal port and a second branch terminal coupled to a second signal port, and a branch control terminal, wherein the switch branch has both an on-state and an off-state to control passage of a radio frequency signal between the first signal port and the second signal port in response to a control signal applied to the control terminal. The radio frequency switch circuitry further includes an isolation inductor coupled between the first branch terminal and the second branch terminal such that the isolation inductor is in parallel with the switch branch, wherein the isolation inductor has a given inductance that provides resonance with a total off-state capacitance of the switch branch in the off-state at a center frequency of the radio frequency signal.
