Development of E-Band 120W Continuous Wave Traveling Wave Tube
A broadband E-band continuous wave (CW) 120W Traveling Wave Tube (TWT) is developed to meet the requirements of high resolution radar. A new type of non-concentric serpentine wave-guide circuit with variable narrow edges (NSWC) and a dual anode long-range electron gun are adopted in this E-band CW TWT. The first prototype tube has been assembled and tested. Within 5GHz operation bandwidth of 81–86 GHz, this TWT provides saturated output power of more than 120.4 W and -1dB compression point powers of more than 88.81W with saturated gain higher than 32.83dB. This work achieves high saturated output power and -1dB compression point powers comparing with other existing E-band CW TWTs.
