Update time: 2009-08-02
Text Size: A A A

 1. Major technical advantages
Undertake national/ministerial longitudinal projects such as National Science & Technology Pillar Program projects, National Major Projects on core electronic devices, pre-research, researches on type series and new products, CAS National Defense Innovation, and be committed to technical innovation and basic applied researches on space traveling-wave tubes and related areas. Solve critical, fundamental and common technical issues in the R&D process of space traveling-wave tube amplifiers for engineering use. Meanwhile take charge of the development and small batch production of broad-band CW traveling-wave tubes, pulsed traveling-wave tubes, and ultra-compact pulsed traveling-wave tube for various key projects and aerospace engineering use. The center has provided over 10 models of space traveling-wave tube amplifiers for our satellites, rockets and manned space projects, as well as over 30 models of traveling-wave tubes for various electronic countermeasures systems, thus made an important contribution to our nation. 

Be equipped with a domestically advanced traveling-wave tube process line; the space traveling-wave tube amplifiers, broad-band CW traveling-wave tubes, and pulsed traveling-wave tubes developed by the center are domestically leading; be capable of small batch production of various models of space traveling-wave tubes and TWT for military use (over 500 per year in average).
