HYBRID O-TYPE TUBE Russian patent published in 2004 - IPC

FIELD: microwave engineering; single- and double-mode microwave tubes.

SUBSTANCE: slow-down of operating spatial harmonic of each c/V_nH section equals slow-down of electron beam c/V_IH = c/_ViIH = … c/V_NH = c/V_e where C is light speed, V_nH is phase speed of operating spatial harmonic of n-th section at its passband frequency f_n; V_e is electron beam speed; b_n speed parameter of each section at frequency f_n + (f₂ - f₁) does not exceed 3 b_I, b_II …, b_n, … b_N ≤ 3. Proposed O-type tube used in developing both single- and double-mode high-power devices has made it possible to reduce output power variation in 8% passband to 1 dB.

EFFECT: reduced output power variation, enhanced electronic efficiency.
