A transformer has 100 turns on the primary coil and is designed to match an impedance from a source of 50 ohms to a load of 200 ohms. How many turns should the secondary coil have?
💡 Hint: Think about how to rearrange the formula and calculate the necessary secondary turns based on the load and source impedance.
Discuss the broader implications of applying transformers in RF designs. What happens if impedance matching is ignored?
💡 Hint: Consider how each component in a system interacts with each other when signals are processed.
