Abstract
A re-entrant microwave resonant cavity comprises a stub. A cylindrical wall, first end walland the stubare integrally formed. A second end wallis defined by a metallization layerdeposited on a printed circuit board substrate. The parts are joined using surface mount soldering processes. The endof the stubdefines a gap. A rostrumfaces the end of the stub. The rostrumis manufactured separately and then fixed to the substrate. A dielectric sphereis located between the endof the probe stuband the rostrum. The dielectric spheremaintains the gap size during use and aids in correct positioning of the parts during manufacture.
