摘要

NEC Network and Sensor Systems, Ltd. has developed a DBS band 1250W peak 750W CW helix Traveling Wave Tube (TWT) for Direct Broadcast Satellite uplink. The TWT covers the full extended DBS band of 17.3 to 18.4GHz. The overall efficiency is greater than 30% at rated power. The measured data of electrical characteristics and the results of two reliability verification tests to ensure high reliability are shown in this paper.
