Abstract
A klystron tube for amplifying signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field focused by a high energy magnet in the RF section of the tube. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. The multistages of the depressed collector are connected to high energy voltage sources of different potentials. The klystron tube with the multistage depressed collector is uniquely used here for the first time in a ground based satellite or terrestrial communications system.
Claims16
A ground based satellite or terrestrial communications system utilizing a high power output vacuum electron device, said vacuum electron device comprising a klystron having a multistage depressed collector that is free of magnetic field reversals.
A ground based satellite or terrestrial communications system, comprising:
- a klystron with a multistage depressed collector that is free of magnetic field reversals;
- a power supply for supplying power to said klystron;
- and
- a control system for controlling the operation of said ground based satellite or terrestrial communications system, said power supply, and said klystron.
A ground based satellite or terrestrial communication system utilizing a high power output klystron, said klystron comprising:
- an electron gun operable to emit electrons;
- a gun magnet enveloping at least a portion of the electron gun operable to focus the electrons into an electron beam;
- an RF interaction region operable to modulate and amplify the electron beam;
- and
- a collector coupled to the RF interaction region, said collector having a collector chamber being free of magnetic field reversals and having a surface configured to disperse and collect the electron beam received from the RF interaction region.
A ground based satellite or terrestrial communication system utilizing a high power output klystron, said klystron comprising:
- cathode means for emitting electrons;
- gun magnet means for focusing electrons from the cathode means into an electron beam;
- RF interaction means for modulating and amplifying the electron beam;
- and
- collector means coupled to the RF interaction means for dispersing and collecting the electron beam from the RF interaction means and for preventing magnetic field reversals within the collector means.
