RADIOFREQUENCY POWER COMBINER OR DIVIDER HAVING A TRANSMISSION LINE RESONATOR

Abstract:

Power combiner/divider includes a transmission line (TL) resonator having an inner conductor, an outer conductor that surrounds the inner conductor, and a cavity between the inner conductor and the outer conductor. The inner conductor and the outer conductor are electrically connected at a proximal end of the TL resonator. The power combiner/divider also includes coupling elements extending through respective openings of the outer conductor and into the cavity. The power combiner/divider also includes a capacitive element connected to at least one of the inner conductor or the outer conductor. The capacitive element capacitively couples the inner conductor and the outer conductor at a distal end of the TL resonator.
