Note that the control grid is completely enclosed by the screen grid. Figure 6.146 shows the schematic symbol of the tetrode. Plate Screen grid 6. Control grid — Cathode — Heater This limitation led to the far wider use of the pentode instead of the tetrode, to be discussed in the next section. The beam tetrode did, however, The circuit symbol for a beam tetrode is shown in Figure 7.37 (b). Pentode The changes to the The best known practical versions of the thyristor tetrode are the BRY39, the 2N6027, and the D13T1, which are virtually identical devices. Figure 18.20 shows the (a) Thyristor tetrode symbol and (b) transistor equivalent circuit. Figure 18.20.The construction.of tetrode is shown in figure. Cut.away view Symbol Fig. : Vacuum Tetrode ln a tetrode electron emission from cathode constitutes a screen grid current as well as plate current. The screen grid current is only a very small part A tetrode is a fourterminal tube that is created with the addition of a screen grid between the plate and the control grid. The function of the screen grid is to The schematic symbol for a tetrode is shown in Fig. C.5. The presence of the screen In addition, tetrode tubes provide a higher gain (amplification) than can be obtained by a triode. The schematic symbol for the tetrode is shown in figure 232. The operation of the tetrode seemed ideal until the phenomenon known as The tetrode vacuum.tube has four electrodes: plate, cathode, control grid and screen grid. 16.26 (a) Tetrode symbol and (b) interelectrode capacitance The interelectrode capacitance of a tetrode is small compared to that of a triode, in which Q What is a tetrode? A Vacuum tubes in which a second grid (screen grid) appears are known as tetrodes. The symbol for the tetrode is indicated in Fig. 420. In a tetrode, to differentiate one grid from the other, the control grid is often called There are beampower tetrodes as well as beampower pentodes. Figure 40 shows the internal structure of a beampower tetrode, with the symbol for this tetrode. b. THEORY. Because the spaces between the grids are lined up, fewer Among the most common multielectrode.tubes are the tetrodes, which have four electrodes (two grids), and the pentodes, which have five Simplified Construction of Tetrode and Schematic Symbol for this reason almost replaced the tetrode.
