Abstract
The plasma radio-frequency (RF) waveguide switch utilizes the RF transmission cutoff frequency property of ionized gas (plasma) to implement an RF switch in waveguide. The plasma RF waveguide switch includes a waveguide defining an inner space and having an input port for receiving an RF signal and an output port, a plasma chamber placed in the inner space, ionizable gas contained in the plasma chamber, and at least one activator configured to activate the ionizable gas into a plasma state. The plasma chamber is self-contained and hermetically sealed, and therefore, the plasma RF waveguide switch does not require an external gas tank or gas supply device. The plasma chamber includes a first dielectric hermetic waveguide window at a side of the plasma chamber and a second dielectric hermetic waveguide window at an opposite side of the plasma chamber.
