Abstract: In a coaxial power grid tube, the control grid lead passes into the envelope of the tube coaxially of and within the cathode lead structure. A cross-over structure is provided within the envelope for passing the control grid structure through the cathode lead structure in insulative relation thereto. The cathode lead structure includes a pair of concentric radially spaced cylinders (double wall) connected together for applying potential to one end of a directly heated thermionic cathode emitter, whereas the other lead for the cathode emitter is disposed in insulative relation within the interior of the double wall cathode lead structure for completely shielding the internal cathode lead from RF energy present in either the grid drive or output RF circuits of the tube.
Abstract translation: 在同轴电网管中，控制栅极引线进入与阴极引线结构同轴并且位于阴极引线结构内的管的外壳。 在外壳内提供交叉结构，以使控制栅格结构以绝缘关系传递通过阴极引线结构。 阴极引线结构包括一对连接在一起的同心径向隔开的气缸（双壁），用于将电位施加到直接加热的热离子阴极发射体的一端，而阴极发射体的另一个引线以绝缘关系设置在 双壁阴极引线结构，用于完全屏蔽内部阴极引线与存在于管的栅极驱动器或输出RF电路中的RF能量。

Abstract: An external anode electron tube having improved conductive cooling means. A hermetically sealed tube envelope is disclosed having a relatively massive annular, generally cup-shaped metallic external anode having a plurality of spaced, annular projections, and a ceramic tubular envelop member hermetically sealed to the ends of the anode projections. An annular, metallic mounting flange is also disclosed having a plurality of spaced sections, each section having a surface coplanar with a surface of each other section. A disc-shaped ceramic header is further disclosed positioned in spaced relation within the annular flange. The header has a plurality of terminal pins projecting therethrough.
