A DC bias is applied to the control grid of vacuum tubes in power amplifiers in order to regulate power.
12.
In other tetrodes one of the grids is a control grid, while the other may have a variety of functions.
13.
When a control grid was added between the cathode and the perforated anode, the device was called a " pliodynatron ."
14.
The negative resistance of older tetrode tubes was around 10k?-20k?, and can be controlled by varying the control grid bias.
15.
The triode was a three terminal device with a control grid that can modulate the flow of electrons from the filament to the plate.
16.
The "'control grid "'is an electrode used in amplifying amplifying vacuum tube, the Audion ( triode ).
17.
By the 1930s, advances in vacuum tube manufacturing had yielded the tetrode, which had reduced control grid to plate ( Miller ) capacitance.
18.
The Additron Tube design by Josef Kates gated electron beams of a fixed trajectory with several control grids which either passed or blocked a current.
19.
The tube is notable for its extremely fine grid, and extremely close control grid to cathode spacing, yielding excellent high-frequency performance.
20.
In such applications, a control grid is typically introduced between the TWT's electron gun and slow-wave structure to allow pulsed operation.
