    Abstract: Two or more signal interaction structures (16,18), which may be klystron or traveling wave structures (32,50), are axially disposed in series between an electron gun (12) and a collector (14) for selectively velocity modulating an electron beam (20) generated by the gun (12) with a microwave input signal (IN1,IN2) and extracting a resulting amplified microwave output signal (OUT1,OUT2) from the beam (20). The interaction structures (16,18) are designed to operate in different frequency bands, for example the X and Ku bands, with only one of the structures (16,18) having an input signal (IN1,IN2) applied thereto at any given time. The interaction structures (16,18) are further designed such that the structures (16,18) which are not being used do not affect the structure (16,18) which is being used.

    Abstract: A klystron is provided for supplying power with optimum efficiency across a variable impedance load. To attain this result, the field in the output cavity of a klystron is detected by a probe. This field supplies the image of the voltage at the terminals of the interaction gap. The signal supplied by the probe is used for adjusting the amplitude of the ultra-high frequency voltage applied to the input cavity so that the voltage of the terminals of the interaction gap remains less than the tolerable maximum whatever the ratio of standing waves reflected back by the output device.

    Abstract: A radio-frequency amplifier includes at least two double-ended electron discharge devices in coaxial-type, radio-frequency cavity-resonator circuits. Each discharge device has a discharge region so that the amplifier comprises a plurality of longitudinally spaced-apart, electrically connected discharge regions. Each of the discharge regions has a cathode with an anode circumscribing the cathode. At least one grid electrode is disposed between the cathode and the anode. A coaxial input transmission line is loop-coupled to an input cavity-resonator circuit and a coaxial output transmission line is loop-coupled to an output cavity-resonator circuit.

    Abstract: A klystron tube is provided with a long drift tube between the last prebuncher interaction gap and the first buncher interaction gap. The length of the long drift tube is such that in a preferred embodiment the ratio of the peak R.F. gap voltage to the D.C. beam voltage is between 1.4 .times. Wq/w and 2Wq/w where Wq is the reduced plasma frequency in radians per second and w = 2.pi. .times. signal frequency. By this means the distribution of the electrons in the beam is improved.
