L-Band Inductive Output Tube
L-Band Inductive Output Tube
US Patent:
2007008, Apr 12, 2007
Filed:
Dec 4, 2006
Appl. No.:
11/633850
Inventors:
Heinz Bohlen - Kehl, DE

Assignee:
Communications & Power Industries, Inc. - Palo Alto CA
International Classification:
H01P 7/06
US Classification:
333227000
Abstract:
An inductive output tube (IOT) operates in a frequency range above 1000 MHz. An output window may be provided to separate a vacuum portion of the IOT from an atmospheric pressure portion of the IOT, the output window being surrounded by a cooling air manifold, the manifold including an air input port and a plurality of apertures permitting cooling air to move from the port, through the manifold and into the atmospheric pressure portion of the IOT. The output cavity may include a liquid coolant input port; a lower circular coolant channel coupled to receive liquid coolant from the liquid coolant input port; a vertical coolant channel coupled to receive liquid coolant from the lower circular coolant channel; an upper circular coolant channel coupled to receive liquid coolant from the vertical coolant channel; and a liquid coolant exhaust port coupled to receive liquid coolant from the upper circular coolant channel.

Assignee:
Communications & Power Industries, Inc.,
International Classification:
H01J025/34
US Classification:
315/003500
Abstract:
An electrode structure for a vacuum tube is formed by having a ceramic insulating body act as the tube wall. Electrode areas are formed on the inside of the tube by coating the inside of the tube wall with a conductor. These electrode areas are then coupled, as necessary, to external electronic circuits. The coupling may be performed by through-wall connections, metallized abutting connections and other conventional means. The ceramic insulating body may be generally cylindrical in shape and may be formed of a material such as aluminum nitride, beryllium oxide, aluminum oxide and the like.
