NEC Network and Sensor Systems, Ltd. Q/V-band Helix TWT for Future High Throughput Satellite Uplink Applications

NEC Network and Sensor Systems, Ltd. has developed a Q/V-band(47.2 - 51.4GHz) 250Wpeak 150Wcw TWT(Traveling-Wave-Tube). This was accomplished with attention to detail in the design of performance and reliability in support of future HTS(High Throughput Satellites) uplink application. This paper presents the summary of this development, which is based on NEC’s vast experience, gained from the Ka-band 500W/550W TWTs, well as the space application TWTs.
