A method for sending a long-term reference picture indicator by an electronic device is described. An epitaxial silicon germanium alloy layer is formed within the gate cavity and on the exposed portion of the silicon fin. A first set of contacts are clamped to a main adapter base which is removably securable to a load board or similar test fixture. Wash spray from the nozzles is directed to impinge sides of the electrode. The first and second lengths are less than one sixteenth of a wavelength at the lowest frequency of operation of the directional coupler.
