🔍 Key Concepts

• Screen grid function in a tetrode vs. a triode • How the screen grid affects capacitance between plate and control grid • Relationship between screen grid and gain (amplification) and neutralization in RF amplifiers

💭 Think About

• Think about what electrical problem the screen grid was invented to solve in triode RF amplifiers. • Ask how adding a screen grid changes the interaction between the plate and the control grid, and what that does to stability and gain. • Consider whether the screen grid’s primary purpose is to increase gain, improve stability, reduce feedback, or some combination of these.

✅ Before You Answer

• Verify what happens to grid-to-plate capacitance when a screen grid is added. • Check whether screen-grid tubes (tetrodes/pentodes) usually require less neutralization than triodes in RF service, and whether this is frequency-dependent. • Confirm whether the screen grid directly enables higher amplification compared with a comparable triode design.
