地球站用高性能小型螺旋线行波管ＮＥＣ公司根据原生产的６ＧＨＺ，７００Ｗ和１４ＧＨＺ，３００Ｗ两种行波管开发出性能更好，体积更小的螺旋线行波管。该管的螺旋线夹持杆采用的是氨化硼（ＢＮ）陶瓷，而不是过去普遍采用的氧化被（ＢｅＯ）陶瓷。因为ＢＮ陶瓷介电常数...
Earth Station with high-performance small spiral traveling wave tube NEC company based on the original production of 6GHZ, 700W and 14GHZ, 300W two traveling wave tube to develop better performance, smaller spiral tube traveling wave tube. Instead of the commonly used oxide (BeO) ceramics used in the past, the helical wire holding bar of this tube uses BN. Because BN ceramic dielectric constant ...
