Sperry RMA #452 (1945) two-cavity klystron. Maximum accelerating voltage 3000 V DC, beam current 150 mA, beam power input 450 W; control electrode 0 to -200 V, max current 3 mA; reflector none. Mechanical tuning printed 2700 to 2330 MHz, reversed; unresolved; electronic tuning 10 MHz; maximum RF output 20–40 W. These are klystron accelerating-electrode/beam ratings, not conventional plate voltage/current/dissipation, so corresponding scalar fields remain null. Heater voltage/current not published in this source.
