WebInductive Output Tube (schematic) Thus the electron beam, after being high-frequency modulated between cathode and control grid and accelerated between … The inductive output tube (IOT) or klystrode is a variety of linear-beam vacuum tube, similar to a klystron, used as a power amplifier for high frequency radio waves. It evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers in radio transmitters. The primary … Meer weergeven The inductive output tube (IOT) was invented in 1938 by Andrew V. Haeff. A patent was later issued for the IOT to Andrew V. Haeff and assigned to the Radio Corporation of America (RCA). During the 1939 Meer weergeven Thermal radiation from the cathode heats the grid. As a result, low-work-function cathode material evaporates and condenses … Meer weergeven Because of the every-household presence of the conventional television picture tube (Cathode-Ray Tube), it may be helpful to think of its principles of operation. Though the IOT does not produce a glowing phosphor output, internally many principles … Meer weergeven • Free-electron laser Meer weergeven • http://www.bext.com/iot-an-old-dream-now-come-true/ • http://www.ebu.ch/departments/technical/… • http://www.davidsarnoff.org/kil-chapter03.html Meer weergeven

Web電晶體的基極至少需要特定的電壓才能導通，同様的，閘極电容需要一定的 電壓 才能充電，讓晶體導通。 同樣的，若要關斷晶體，也需要釋放電容器上的電荷，因此閘極电容也需要放電。 在功率晶體導通或是關斷，不會立刻就切換到完全導通或是完全不導通的狀態，切換過程中可能會有短暫時間通過大 電流 ，且功率晶體上有較大的電壓。 因此在切換時會 … Webinductive output tubes, klystrons, magnetrons, and gyrotrons with power outputs greater than 10 kW c.w. or 100 kW pulsed at frequencies from 50 MHz to 30 GHz ... The output power available from such a tube is limited by the maximum current density available from the cathode and scrap 10k gold
