<p>A resonant cavity (20, 40) is coupled in series with an output waveguide (30) of a klystron (10) in order to enhance power within an operating band of the klystron (10). The response characteristic of the resonant cavity (20, 40) enhances the power at certain frequencies within the operating band of the klystron (10), e.g., at the high or low ends of the operating band, by intentionally creating a power mismatch at these certain frequencies while providing minimal effect on the power at other frequencies of the band. The resonant cavity (20, 40) is inductively coupled to the output waveguide (30) through an iris (22) that sets the phase of the reflection by virtue of its location in relation to the klystron output gap (9) and the magnitude of the reflection by virtue of its size. A tuning apparatus (24, 26, 28, 29) may also be used for tuning the resonant frequency of the resonant cavities (20, 40). Plural resonant cavities (20, 40) may also be utilized to provide power mismatches at plural portions of the klystron operating band.</p> |
