Development of an X-band 800W pulsed mini-TWT for active phased array radar modules

This paper describes our successful development of a mini-TWT (miniature travelling wave tube) for active phased array radar systems delivering high RF output power of more than 800W over the frequency range of 9 to 10GHz with a high overall efficiency of 46%. This mini-TWT achieves compact size in a package of 20mm(W) × 20mm(H) × 195mm(L) with a lightweight of 0.4kg.
