Subelement G6
Circuit Components
Each group below is a real teaching page, not just a topic list. Read the explanation, use the checklist to make sure the main ideas are sticking, then quiz that group if you want an immediate check.
G6A
Passive Parts, Diodes, Transistors, Tubes & Batteries
A schematic becomes easier when each component is associated with the job it usually performs: limit, store, switch, amplify, rectify, regulate, or supply energy.
Study G6A →G6BICs, MMICs, Displays, Connectors & Ferrites
Modern radios package whole functions into integrated circuits, but connectors, ferrites, and interfaces still determine whether RF gets cleanly from one block to the next.
Study G6B →Close the loop
