A resonator system is presented that has first and second cavity resonators for use in an RF amplifying system employing an RF amplifier device having an output circuit and an RF signal broadcasting antenna coupled to the output circuit. The resonators are interposed between the amplifying device output terminal and the antenna. The first resonator is comprised of a transmission line being a length of two coaxial conductors and tuned to the 3rd harmonic of the operating frequency (3fo). Each resonator has first and second opposing ends with the first end being an open end and the second end being a shorted end. The open end of the first resonator is connected to the output terminal of the RF amplifying device. The second resonator is connected in series with the first resonator and is tuned to the fundamental operating frequency (fo).
